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

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

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

Answer:

The amount of money that  all five brothers have combined is:

                  $ 60

Step-by-step explanation:

Let the total cost that all the five brothers have combined be: $ x

Also, it is given that Peter contributes 30% of the total money and it constitutes to $ 18.

This means that 30% of total money=18

This means that:

[tex]\dfrac{30}{100}\times x=18\\\\\\\dfrac{3}{10}x=18\\\\\\3x=180\\\\\\x=60[/tex]

              Hence, the total money is:

                              $ 60
