Answer 1

total money is 20$

Step-by-step explanation:

let the money Ben spent is a and the money he saved is b.

Given that the ratio of money he spends (a) to money he saves (b) is 3:1 i.e

a:b = 3:1.

also given that he has spent 15$ so a = 15$.

15:b = 3:1

product of extremes = product of means

15*1 = b*3

rearranging

b = 15/3 = 5$.

so he has saved 5$.

total money hiven to ben was 15$ + 5$ which is 20$.
