given: Peter bought 4 toys and the price of the first 3 toys were $30, $15 and $18 and the average price of all the 4 toys were $25.
to find: find the value of the fourth toy
solution: let the price of the 4th toy be x
A/Q
the average of all the 4 toys was $25
now,
we know that
average =sum of all 4 toys/number of toys
25=30+15+18+x/4
25=63+x/4
100=63+x
100-63=x
37=x
therefore, the value of the 4th toy is $37.
