Mae Ling earns a weekly salary of $335 plus a 5.0% commission on sales at a gift shop. How much would she make in a work week if she sold $4,200 worth of merchandise?
Answer:
Mae Ling earns a weekly salary of $335.
She also earns 5.0% commission on sales. If she sold 4200 worth of merchandise, she would get 4200 x 5/100 = 210$
Totally, she earns 335 + 210 = 545$
Hope this helps!
:)
Answer:
$545
Step-by-step explanation:
Commission is basically the percentage of the profit made that the salesperson gets to keep. The weekly salary is a fixed amount, so that won't change.
Here, Mae Ling sells $4200 worth of merch, which is the profit made, so the commission will be 5% of that:
5% * 4200
Remember that % is just "out of 100", so 5% = 5/100:
(5/100) * 4200 = $210
Add this to the salary:
335 + 210 = $545
She would make $545.

mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. What was the cost of each box?
Which equation represents this scenario?
a. 10r + 5 + 64
b. 5(10r) = 64
c. 10r - 64 = 5
d. 5 - 10r = 64
Let r represent cost of each box.
We have been given that Mia bought 10 boxes of brownies. So cost of 10 boxes would be [tex]10r[/tex].
We have been given that Mia bought 10 boxes of brownies at the store for a total of $64. The tax on the purchase was $5. So the total cost of 10 boxes would be cost of 10 boxes plus tax.
We can represent this information in an equation as:
[tex]10r=64+5[/tex]
We can subtract 64 from both sides as:
[tex]10r-64=64-64+5[/tex]
[tex]10r-64=5[/tex]
Therefore, our required equation is [tex]10r-64=5[/tex] and option 'c' is the correct choice.

Help please!!!!! I hate this part of volume of pyramids :/
Answer:
h = 6 cm
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = [tex]\frac{1}{3}[/tex] Ah ( A is the area of base and h the height )
Here A = 3 × 2 = 6 cm² and V = 12 , thus
[tex]\frac{1}{3}[/tex] × 6 × h = 12, that is
2h = 12 ( divide both sides by 2 )
h = 6 cm
A circle is centered at T(-6,3)T(−6,3)T, left parenthesis, minus, 6, comma, 3, right parenthesis and has a radius of 111111.
Where does the point N(3,-3)N(3,−3)N, left parenthesis, 3, comma, minus, 3, right parenthesis lie?
Answer:
The point N lies inside the circle
Step-by-step explanation:
A circle is centered at the point T(-6,3) and has a radius of r=1.
To determine if the point N(3,-3) is inside or outside the circle, the distance between N and the point T must be lower than 11.
To calculate the distance between points T and N you use:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
where x1 and y1 are the coordinates of T, and x2 and y2 the coordinates of N.
[tex]d=\sqrt{(3-(-6))^2+(-3-3)^2}=\sqrt{9^2+6^2}=10.81[/tex]
d < 11
The distance d is lower than the radius of the circle. Hence, the point N lies inside the circle

Additionally, the diagonals of a rectangle bisect each other.
Having said that, the choices A, C and D can help to demontrate that the figure is a rectangle.
You prove that abcd is a rectangle by the options A, Cand D.
We have given that figure ABCD
we have to determine that ABCD is a rectangle.
Remember that a rectangle is a quadrilateral which have its opposite sides equal and parallel, and all its internal angles are 90°.
So, those are all the characteristics we need to demonstrate.
What is the rectangle?A rectangle is a quadrilateral with four right angles. It can also be defined as an equiangular quadrilateral, since equiangular means that all of its angles are equal or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
Additionally, the diagonals of a rectangle bisect each other.
Having said that, choices A, C, and D can help to demonstrate that the figure is a rectangle.

The Zearn Fair charges $1.75 for entrance and $1.05 for each ride. Mr. Sawicki brings $20 with him to the fair. What is the greatest number of rides Mr. Sawicki can go on if he uses $2.50 for food? How much money can Mr. Sawicki spend in total
Step-by-step explanation:
So
Total money = 20
Entrance fee = 1.75
Food = 2.50
Ride = 1.05
Amount spend = 1.75 + 2.05 = 3.8
Left for rides = 20 - 3.8 = 16.2
So rides = 16.2 ÷ 1.05 = 15
I think atleast 15 rides

△GHI ≅ △KLM what is the m∠KLM
Answer:
64°
Step-by-step explanation:
Both triangles represent a right angle by the small box in the angle.
Right angles = 90°
Since the triangles are congruent, then they would have the same measurements in their angles an sides. All triangles also have a sum of 180°. So, we can just subtract (26 + 90) from 180 to get the third angle.
180 - (26 + 90)
180 - 116
64
So, the m∠KLM is 64°.

Sandra saves 9% of her salary for retirement this year salary was 1000 more than in her previous year and she saved $4050 what was your salary in the previous year
Answer:
$44,000
Step-by-step explanation:
The statement indicates that Sandra saves 9% of her salary and she saved $4,050 this year. That means that the 9% of her salary, x, is equal to $4,050. You can write the following:
x*0.09= 4,050
Now, you can isolate x to find her salary this year:
x=4,050/0.09= 45,000
Then, you have that this year salary was 1000 more than in her previous year. As you have found her salary for this year, you can subtract 1,000 from it to find her salary in the previous year:
45,000-1,000= 44,000
According to this, the answer is that her salary in the previous year was $44,000.

Preston signed up for overdraft protection at his bank. This bank charges an overdraft fee of $30 for insuffcient funds. Preston has a balance of $50. He then purchased a pair of tennis shoes using his bank debit card. If the total charge for the tennis shoes is $52, what will be Presont's new balance?
Answer:
-$32
Step-by-step explanation:
Given that
Overdraft fee = $30
Preston Balance = $50
Total expenditure = $52
As per the given question the solution of new balance is provided below:-
To reach the new balance of Presont's first we need to find out the overdraft balance which is as follows:-
Overdraft balance = Balance - Total expenditure
= $50 - $52
= -$2
Since there is a balance of $50 but Pretson purchased for $52 value that results -$2 overdraft balance. In order to determine the new balance we simply added the overdraft fee and overdraft balance which is shown in negative sign.
Now according to the question the New balance of Presont's = Overdraft balance - overdraft fee
= -$2 - $30
= -$32
