Hi
three more quarters than dimes and twice as many nickels as quarters
Let x,(x+3), 2(x+3)represent the number of dimes, quarters and nickels respectively
Question states***Note: Cents makes sense
10x+ 25(x+3)+ 5*2(x+3) = 375 CENTS
Solving for x
45x + 75 + 30 = 375
45x = 270
x = 6, the number of dimes. 9 Quarters and 18 Nickels
CHECKING our Answer***
10*6 + 25*9 + 5*18 = 60 + 225 + 90 = 375 or $3.75
