a.Write an equation to describe this equation. Let t represent the number of t-shirts ordered and c represent that total cost of the order.

b. Write an equation that you can use to determine how many t-shirts Nadine ordered if her total cost was $151.75.

c. Write a sentence to describe how to apply inverse operations to solve your equation from part (b). Then, solve the equation.

d. How many t-shirts did Nadine order if her total cost was $151.75?

Answer 1

Answer:

Step-by-step explanation:

let the number of t shirts ordered = t

let the total cost of the order = c

therefore, total cost / number of t shirts

= t/c

= $151.75/$10.95

= 13.85=14

she ordered 14 t shirts

since she had a coupon

= $151.75-$12.50

= 139.25

Therefore, she ordered 14 t shirts and her total amount was $139.25
