Question

Juan has 20 books to sell. He sells the books for $15 each.

The amount of money Juan makes from selling x books is represented by a function.

Answer 1

answer: y=20x
step by step explanation: y is equal to the total amount earned for selling the books. There are 20 books being sold for (x) amount. So you would have y=20x. Now if you want to solve it to see the total amount earned you would simply plug in 15 for x, and solve from there. the total amount earned would be 300. but the function is still y=20x
