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

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

Step-by-step 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
