Question

Bo paid bills with 1/2 of his paycheck snd put 1/5 of the remainder in savings. The rest of his paycheck he divided equally among the college accounts of his 3 children.
A. what fraction of his paycheck went into each childs account?
B. If Bo deposited $400 in each childs account, how much money was in Bo's original paycheck?

Answer 1

For college, 1-1/2-1/5 = 3/10. Divided by 3 children, 3/10 /3 = 1/10

B. 400 = 1/10 of the total (from above), so 400 = x/10. x = 400*10 = 4000
