Q:

Peter and his four brothers combined all of their money to buy a video game. If 30% of the total money is Peter's, and $18.00 of the total money is Peter's, how much do all five brothers have combined?

Accepted Solution

A:
Let the total amount combined be 100% and at $x.

Then, Peter's contribution of $18 represents 30% of $x.
Therefore,

30% of $xΒ -----> $18
100% of $x ---> $x
Then,
x= (100*18)/30 = $60
