The total cost of making a daily taco special for a restaurant is represented by the function C(t)=2.5t+1, where t is the number of tacos made. How does the total cost change for every taco special the food truck makes? a: $1 b: $2.50 c: -$1 d: -$2.50
Given:
The total cost of making a daily taco special for a restaurant is represented by the function
[tex]C(t)=2.5t+1[/tex]
Where t is the number of tacos made.
To find:
The total cost change for every taco special the food truck makes.
Solution:
We have,
[tex]C(t)=2.5t+1[/tex]
Here, 1 is a constant because it is free from the variable and 2.5 is the coefficient of t.
It means, 1 represents fixed cost of making tacos but 2.5t changes with respect to t. Thus, 2.5 represents the addition cost of every taco special the food truck makes.
So, $2.5 is the total cost change for every taco special the food truck makes.
Therefore, the correct option is b.
Natalie is on her school's swim team. Last year, she swam the 300-meter freestyle in 3 2/3 minutes. This year she swam a shorter distance of 200-meter freestlye in 3 minutes. What is her speed for per hour for each hour for each distanc
Answer:
4909 m/hr
6000 m/hr
Step-by-step explanation:
Last Year :
Distance = 300 m
Time = 3 2/3 minutes
Speed per hour = distance / time
Time in hour = 11/3 ÷ 60 = 0.0611111 hour
300 / 0.0611111 = 4909.0918 m /hr
= 4909 m/hr
This year :
Distance = 200 m
Time = 3 minutes
Speed per hour = distance / time
Time in hour = 3 ÷ 60 = 0.0333333 hour
200 / 0.0333333 = 6000.0060 m /hr
= 6000 m/hr

The cost of a set of DVDs after a 25% markup can be represented by the expression c+0.25c . Simplify the expression.
Answer: 1.25c
Step-by-step explanation:
The original cost of the DVDs is given as c.
The cost of the DVDs after a 25% markup is: c + 0.25c to show that 25% of c was being added to c to increase the price.
As both numbers in the equation have the same variable attached, they can be added. c is assumed to be 1c when it stands alone.
= c + 0.25c
= 1c + 0.25c
= 1.25c
Find the volume of the solid. Please help!!
Answer:
132 cm³
Step-by-step explanation:
Two different ways to calculate:
7×6×6= 252 "would-be" total volume.
5×4×6=120 "missing chunk" subtract that.
252-120= 132 cm³ remaining total
OR
7×2×6=84 vertical part
4×2×6=48. horizontal part. add them
84+48= 132 cm³ Total volume

The x-axis is 10 units.
From the graph,
(2, 20) means 20 miles in 2 hours.
Thus,
The total number of miles is 100.
The total number of hours is 10.

Shen invested in a savings bond for 2 years and was paid simple interest at an annual rate of 2% the total interest that he earned was $28 how much did he invest 
Answer:
Principal = $700
Step-by-step explanation:
Simple interest = principal × rate × time
Simple interest = $28
Rate = 2% = 0.02
Time = 2 years
Principal = x
Simple interest = principal × rate × time
28 = x * 0.02 * 2
28 = 0.04x
x = 28/0.04
x = $700
Principal = x = $700
Solve for x. (6x - 7) (10x - 47)

Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?
Answer:
65% of the orginal fee or $130.
Step-by-step explanation:
You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:
1: 100% = 10% + 25% + 65%
2: 200 = 20 + 50 + 130
3: 200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)
All of them basically mean the same thing it is just a matter of how you need it written.
Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.
Rodney has to pay $200 in three installments.
The third installment will be:
= Percentage in total - Percentages paid already
= 100% - 10% - 25%
= 65%
The third installment is therefore:
= Percentage to be paid x Amount
= 65% x 200

AB, CD and EF are straight lines.
AB is parallel to CD.
work out the size of angle y.
Answer:
y = 108°
Step-by-step explanation:
Since, line AB is parallel to line CD,
By the definition of corresponding angles,
m∠FPB = m∠FQD
(2x + 16)° = (3x - 12)°
3x - 2x = 16 + 12
x = 28
(3x - 12) = 3(28) - 12
= 72°
m∠FQD + m∠EQD = 180° [Linear pair of angles]
72° + y = 180°
y = 180 - 72
y = 108°

We need to find 2 numbers that add to make -5 and multiply to make -6.
We already have the numbers infront of us, so by process of elimination we can remove B and D.
For the numbers, we need a positive number and a negative number (two negatives make a positive). We can eliminate C because at first -3 multiplied by 2 is -6. However, when -3 is added to 2 we get -1.
If we expand A, it makes the expression that needs to be factorised because...
-6 × 1 = -6
-6 + 1 = -5
So expanding it properly we get.
x² - 6x + x - 6
Simplify.
x² - 5x -6

a farmer is creating a budget for planting soybeans and wheat. planting soybeans costs $200 per acre and planting wheat costs $500 per acre. He wants to spend no more that $100,000 planting soybeans and wheat. Write an inequality to describe the constraints. specify what each variable represents
The inequality that represents the constraint is as follows;
200x + 500y ≤ 100000
How to solve inequality?The inequality to describe the constraints is as follows;
Therefore,
let
x = acre of land use to plant soya beans
y = acre of land use to plant wheat
Therefore,
200x + 500y ≤ 100000
Hence, the inequality that represents the constraint is as follows;

Answer:
200x + 500y ≤ 100000
Step-by-step explanation:
Given ,
The cost of planting soybeans is $ 200 per acre
The cost of planting wheat is $ 500 per acre
The maximum amount he can spend for planting is $ 100,000
Let's assume
x = acre of land use to plant soya beans
y = acre of land use to plant wheat
We know that ,
If 'a' is the cost spend on unit item and 'b' is the number of items the total cost will be a * b
So the total amount spend for planting will be,
200x + 500y
As the amount spend cannot exceed a maximum of $ 100,000 ,
200x + 500y should be less than or equal to 100,000
Therefore we can mathematically represent it using the inequality ≤ as,
200x + 500y ≤ 100000
Hence, the inequality that represents the constraint is as follows;
200x + 500y ≤ 100000
