For one child, a childcare facility charges $350 per month for preschool and $5.00 per hour for each additional hour for after-s

Hatshy [7]

Answer:

D. 80

Step-by-step explanation:

We have the following function :

$f(h)=350+5h$ (I)

Where $f(h)$ is the monthly fee for after - school care and preschool.

Where $h$ represents the number of hours spent in after - school care.

We know that the total monthly bill for one child was $750 ⇒

$f(h)=750$

Using (I) we will find the value of the hours '' $h$ '' that verifies the expression ⇒

$f(h)=750=350+5h$ ⇒

$750=350+5h\\750-350=5h\\400=5h\\h=\frac{400}{5}=80$

We find that the value of the hours '' $h$ '' is 80 hours.

The total number of hours the child spent in after - school care is D. 80
