Answer:
20
Step-by-step explanation:
Given that: $3.25 in dimes and nickels were distributed among 45 boys.
1 nickel = $0.05
1 dime = $0.10
Let number of coins of dimes be x and the number of coins of nickel be 45-x.
Hence,
0.10x + 0.05(45-x)=3.25
0.10x+2.25-0.05x=3.25
0.05x=3.25-2.25
0.05x=1
x= 1/0.05
x=20
45-x
45-20=25
