Jonah's dad told him if he mowed the lawn all summer, he would receive a set amount of money up front, plus a payment
for each time he mowed. After 2 weeks, Jonah had earned $120 and after 5 weeks he had earned $165. How much money
did Jonah receive up front? How much did he carn every time he mowed the lawn? Graph the equation to show that it is a
linear function.
