Answer:
Frankie will need to babysit for 4.4 time.

Money saved = $30
Total money Frankie wants to save for a skateboard = $52
Amount of money to be saved =
Total amount of money Frankie wants to save for a skateboard - Money saved already

Thus, we can write the equation:
Thus, Frankie will need to babysit for 4.4 time.
