7-110.

Jeanine earns $5.00$ an hour babysitting her neighbor’s three children. Homework Help ✎

1. How much will Jeanine earn if she starts at $7:30$ p.m. and ends at $12:30$ a.m.?

How many hours did Jeanine work? $5.00$(number of hours) = total earnings

2. How much will she earn if she starts at $10:30$ a.m. and ends at $2:00$ p.m.?

Jeanine worked $3.5$ hours.

3. One day, Jeanine earned $37.50$. How many hours did she work?

$\frac{37.50}{5}=?$

Can you do this in your head? $2.50$ is half of $5.00$. $35.00$ is $2.50$ less than $37.50$.
