Question

sally has 200$ in her checking account and gets paid 15$ an hour for babysitting kent has $245 in his checking account and gets paid $12 an hour for baby sitting how many hours do kent and sally need to work to have the same amount on money in their checking account

Answer 1

Sally and Kent would have to each work a total of 15 hours to have the same amount of money in their checking account.

Explanation:

Set up equations.

x = hours, T = total $

Sally:

T = 200 + 15x

Kent:

T = 245 + 12x

Set both equations equal to each other.

200 + 15x = 245 + 12x (subtract 200 from both sides)

15x = 45 + 12x (subtract 12x from both sides)

3x = 45 (divide both sides by 3)

x = 15
