Answer with Step-by-step explanation:
Suppose we make $12 an hour as a lifeguard at the community pool.
Let h represent the number of hours you work a week.
Amount of money we earn in 1 hour=$12
Amount of money we earn in h hours=$12h
Hence, expression that represents the amount of money you earn in a week is:
12h
Now, let h=15
Then, amount of money we earn in a week working for 15 hours=12×15
=$180
Hence, amount of money we earn in a week when h=15 is:
$180
