Answer 1

Given :-

• A daycare charges a base fee of $25 per week plus $3/hour for a child.

To Find :-

• To write a equation that relates the weekly charge C (in dollars) to the number, x, hours, that a child is in daycare .

Solution :-

According to the question ,

• The base price is $25 per week . And per hour charge is $3/hour .

So as per the question if we assume that the babysitter looked after the child for x hours in a week then , the total charge will be ,

→ Charge = $3/hr * x hr= $3x

So the total cost for a week , will be ,

→ Total cost = Base price + Charge

→ Total cost = $25 + $3x

And in the question we are told to assume total cost to be $C . Therefore ,

→ $C = $ (25 +3x)

→ C = 25 + 3x

Hence the required equation is C = 25 + 3x.

I hope this helps.
