1) Tommy mows lawns and cleans pools during the summer. He earns $20 per lawn and $9 per

pool. He needs $1500 to buy a car from his friend. If Tommy plans to mow 41 lawns this
summer, how many pools must he clean to earn at least $1500?

Answer:

Explanation:


20L+9P\ge 1500,\ L=41\\ \\ 20(41)+9P\ge 1500\\ \\ 820+9P\ge 1500\\ \\ 9P\ge 680\\ \\ P\ge 75.6\\ \\ P=76
