Hey there!
Knowing that Sarah earns 7.50 dollars for every hour she babysits, we need to figure out how much she makes after babysitting for 3.5 hours.
To do this, you must multiply her unit price, $7.50, with the number of hours, 3.5.
This expression would look like this:
7.50*3.5
When you simplify, you should get $26.25 as your final answer.
