David has two jobs. He earns $8 per hour babysitting his neighbor’s children and he
earns $11 per hour working at the coffee shop. Write an inequality to represent the
number of hours, x, babysitting and the number of hours, y, working at the coffee shop
that David will need to work to earn a minimum of $200. David worked 15 hours at the
coffee shop. Use the inequality to find the number of full hours he must babysit to reach
his goal of $200.
