HELP ME PLSS!?!?

In the mall you receive a coupon for $5 off of a pair of jeans when you arrive at the store you find that all jeans are 25% off

.let x represent the original cost of the jeans
.the function f(x)=x-5 represents the cost of the jeans if you use the coupon
.the function g(x)=0.25x represents the cost of the jeans if you apply the store discount of 25% first


Write a function:j(x) that represents how much you would pay if you use the store discount first followed by the mall coupon??

Answer:

j(x) = f(g(x)) = f(0.25x) = 0.75x - 5
