a. Write and graph an equation in two variables that represents the total cost of ordering the shirts.
For this case, the first thing we must do is define variables:
c = total cost
x = x number of shirts.
The equation that adapts to the problem is:
c (x) = 10x + 20
Answer:
c (x) = 10x + 20
b. Choose an ordered pair that lies on your graph in part (a). Interpret it in the context of the problem.
Let's choose the next ordered pair:
(x, c (x)) = (0, 20)
We verify that it is in the graph:
c (20) = 10 (0) + 20
c (20) = 20 (yes, it belongs to the graph).
In the context of the problem, this point means that the cost per shipment is $ 20
Answer:
(0, 20)
Cost per shipment is $ 20

Answer:
1. £123120
2. £13.69
3.
4. £1200
5. £105
Step-by-step explanation:
1. 108000 multiplied by 114% = 123120
2. 18.5 multiplied by 1-0.26 = 13.69
3.
4. x (1.65) = 1980
x=1200
5. 113.4 = 1.08x
x= 105

Answer:
314in²
Step-by-step explanation:
Given : Radius of the circle r=10 inches
A = 3.14 x 10²
A = 3.14 x 100
A = 314in²
The answer is -4.4, -2 1/2, -.5, 1/2, 1.5, 3.8
Explanation:
If we converted all the numbers to decimals it would look like this:
1.5 = 1.5
1/2 = .5
-2 1/5 = -2.5
-.5= -.5
3.8 = 3.8
-4.4 = -4.4
Then you would just arrange them from least to greatest starting with -4.4 and ending with 3.8.
Hope this helps!
