a high school student works two summer jobs . One at a coffee shop and one at a grocery store. The coffee shop pays 10$ an hour
and the grocery store pays 84 an hour. He wants to earn $800 per month. If he works 60 hours a month at the coffee shop, what is the LEAST number of hours he can work at the grocery store to meet his goal?
That's $600....so....he needs 200 more ..he'll need to work 3 hours at the grocery store...giving him a total of =252......and $852 gives him 52 extra dollars :)
