Question

You are making curtains by alternating strips of colored fabric and patterned fabric. The solid fabric costs $0.99 per strip and the patterned fabric costs $1.25 per strip. You need 7 strips for one curtain. Write an equation that gives the total cost c as a function of the number n of solid colored strips used. Then find the total cost if you use 3 solid colored strips.

Answer 1

It always requires 7 strips for one curtain. the cheapest alternative is to have only $0.90 strips, the most expensive is having one made from all $1.25 strips.

we should write an equation to mirror the parts of the cost. we tell the function how many colored strips we are willing to sacrifice for the curtain, and it gives back the total cost.
