Answer:
65 girls
Step-by-step explanation:
325/25=13 13x5=65
Write the situation as a simultaneous eqution:
x+y=87
10x+5y=545
Now solve for y by multiplying the whole of the first equation by the coefficient of x:
10x+10y=870
10x+5y=545
5y=325
y=65 nickels in the box
x+y=87
x=22 dimes in the box
To prove this is correct, we do (10 x 22)+(5 x 65)=545 cents ($5.45)
