pat spent 50% of his money in one shop and 25% of what was left in another shop.he had £12 left. what fraction of his money had he left and how much had he at first.

Reiny
amount spent in second shop = (1/4)(1/2) = 1/8
so in both he spent: 1/2 + 1/8 = 5/8
leaving him with 3/8
3/8 x = 12
x = 32
He started with £32
check:
he spent 1/2 is 1st store leaving him with 16
he spent 1/4 of that or 4 in the 2nd store.
That leaves him with 164 = 12
