A piggy bank contains the same number of quarters, nickels, and dimes. The coins total $4.40. How many of each type of coin does the piggy bank contain?

Respuesta :

If x is a number of quarter, and x is a number of dimes, and x is a number of nickels. $4.40=440 cents.
Then

25x+10x+5x=440
x(25+10+5)=440
x*40=440
x=440/40
x=11

11 quarters, 11 dimes and 11 nickels.
