Answer:
$57.75
Step-by-step explanation:
There is a direct proportionality relationship between the amount he earns and the time he spends babysitting.
As the number of hours increases, the time increases at a fixed rate.
If the time is t and the amount earned f
then,
f ∝ t
33 = k(4) where k is the constant of proportionality
k = 33/4
f = 33/4 (t)
The amount he will earn if he babysits for 7 hours
= (33/4) × 7
= $57.75
