John took all his money from his savings account. He spent $48 on a radio and 3/8 of what was left on presents for his friends. Of the money remaining, John put 2/3 into a checking account and the last remaining $100 was left to charity. How much money did John originally have in his savings account?
John originally had $400 in his savings account.
totally useless to just state an answer, Mr bot, especially if it is WRONG
original ---- x
after radio, amount left = x-48
after gift for friends, amount left = (5/8)(x-48)
after putting 1/3 of that into charity,
amount left = (2/3)(5/8)(x-48)
but this is 100
(2/3)(5/8)(x-48) = 100
(5/12)(x-48) = 100
x-48 = 240
x = 288
check: start -- 288
48 spent on radio leaves 240
3/8 of that on presents = 90, leaves him 150
1/3 of that is 50 for charity, leaves him 100
my answer is correct, the bot, as usual for non-trivial questions, is WRONG
