Answer:
$57.84
Step-by-step explanation:
Balloons needed = 168
Cost of 36 balloons per pack = $11.88
Cost of 12 balloons per pack = $5.16
cost per balloon
36 per pack = $11.88 / 36
= $0.33
12 per pack = $5.16 / 12
= $0.43
In order to minimize cost, she should buy as many packs of 36 per pack balloon
36 per pack × 1 pack = 36
36 per pack × 2 packs = 72
36 per pack × 3 packs = 108
36 per pack × 4 packs = 144
36 per pack × 5 packs = 180
The required number of balloons is 168
So, the number of possible 36 packs to buy is 4, that is, 144 balloons
Balloons remaining = 168 - 144
= 24
Possible packs of 12 balloons per pack possible is
12 per pack × 1 pack = 12
12 per pack × 2 packs = 24
Therefore, Megan needs to buy 4 packs of 36 balloons per pack and 2 packs of 12 balloons per pack
Cost of 4 packs of 36 balloons per pack = 4 × $11.88
= $47.52
Cost of 2 packs of 12 balloons per pack = 2 × $5.16
= $10.32
Total cost = $47.52 + $10.32
= $57.84

a roofer charges $60 for the first hour of service call and $25 per hour for each additional hour. The roofer also charges a fee for all materials used plus 30% over the cost of the materials. Let r-roofer's cost of materials and h= number of hours worked. What expression could be used to find the cost of a service call
Answer:
y=60+25h+0.3rStep-by-step explanation:
let y be the total charges
given that the hour is h
and the cost for raw material is r
therefore
1. The first hour of service call = $60
2. For each additional hour= 25h
3. 30% over the cost of the materials.= 30/100*r=0.3r
total charges
y=60+25h+0.3r
therefore the expression is
y=60+25h+0.3r

Find the values of x, y, and z. The diagram is not to scale.
Answer:
95 = x
85 = z
75 = y
Step-by-step explanation:
**remember** all triangles contain 180 degrees
this means that the triangle to the left should add up to 180 to we can set up this equation
180 = 60 + 25 + x
180 = 85 + x
95 = x
now **remember** a flat line is 180 degress so x + z is 180... we can set up this equation:
x + z = 180
plug in x = 95 from before
95 + z = 180
z = 85
**remember** again that a triangle in 180 degrees so for the right one we can set up this equation by pluggging in the z=85
180 = 20 + 85 + y
180 = 105 + y
75 = y
Answer:
first option
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , thus
x = 180° - (60 + 35)° = 180° - 95° = 85°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
z is an exterior angle of the triangle , thus
z = 60° + 35° = 95°
Using the sum of angles in a triangle, then
y = 180° - (95 + 20)° = 180° - 115° = 65°
Thus
x = 85°, y = 65°, z = 95°

convert 8/3 to a mixed number
============================================
Work Shown:
8/3 = (6+2)/3
8/3 = 6/3 + 2/3
8/3 = 2 + 2/3
8/3 = 2 & 2/3
The whole part is 2. The fractional part is 2/3.
-----------
Another way you could do the problem is to use long division as shown in the diagram below.
The result of the long division is
8/3 = 2 remainder 2
The quotient 2 forms the whole part and the remainder is the numerator of the fractional part 2/3.
So that's another way to get 2 & 2/3
An electrician charges an hourly rate of $50, but also charges a fixed fee for making house calls regardless of time spend on the job. One day, the electrician earned a total of $250 for a 2 hour job. Write an equation for C,C, in terms of t,t, representing the total cost of the electrician's services if the electrician spends tt hours at the house working.
Answer:
C=50t+150
Step-by-step explanation:
From the information given, the equation will need to show that the total cost of the electrician services would be equal to 50 that is the hourly rate for the number of hours spent working plus the fixed fee:
Fixed fee=250-(50*2)=250-100=150
According to this, the equation would be:
C=50t+150, where C is the total cost of the electrician's services and t is the number of hours spent working.

Answer:
Ok, so first, at the end of the equation, It says "+ 4" , right? So you put a point on positive 4 on the y-axis (the one that goes up and don, the vertical line.). Then, 2x means that's your slope, but since your graph only goes up to five, you gotta count down ward. So, go down from your point on the y-axis (4) twice and over to the LEFT (<--) once. Plot your point where you end up. then use a straightedge like a ruler, and connect your two points on the graph, and you have your line!

which linear inequality is represented by the graph graph
Answer: choice A
Step-by-step explanation:
The linear inequality represented by the graph is y≥1/3x-1
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Let us find slope of line passing through points (0, -1) and (3, 0)
Slope = 0+1/3
=1/3
y intercept we have to find
0=1/3(3)+b
b=-1
So equation of line is y=1/3x-1
As the shading is away from origin, we use the greater than or equal to symbol.
y≥1/3x-1
Hence, the linear inequality represented by the graph is y≥1/3x-1
