Question

The Miller's are comparing babysitting services for their two children.

The Babysitter's Block charges a rate of $15 an hour per child plus an initial fee of $25 per household.


Super Sitters charges a flat rate of $20 an hour per child.


For ________hours of service, both babysitting services would cost the same.

Answer 1

For 5 hours of service, both babysitting services would cost the same.

Answer 2

After 5 hours of service, both babysitting services would cost the same.

Explanation:

Babysitter's Block: y = 15x + 25

Super Sitters: y = 20x

15x + 25 = 20x

Subtract 15x from both sides;

25 = 5x

Divide both sides by 5;

x = 5
