Question

Joe is mowing lawns to buy a new car. For every lawn that he mows he earns $20. Joe charges a one time clean up fee of $50 before he takes on a new client. The function that Joe uses to determine how much he will make is: f(x) = 20x + 50. If Joe mows 5 lawns how much will he make?
$100
$120
$150
None of the choices are correct.

Answer 1

So x is the number of lawns he mows right? and for each one he mows, he goets 20 dollars. So using the function they've given you, it would be f(5) = 20(5) + 50. What's 20 *5?

Answer 2

a?

Answer 3
