Mary has $4.00 in nickels, dimes, and quarters. If she has twice as many dimes as quarters and forty-seven more nickels than dimes, how many coins of each type does she have?
Answered by Reiny
number of quarters --- x
number of dimes ---- 2x
number of nickels ---- 2x+47

25x + (10)(2x) + 5(2x+47) = 400
solve for x, then sub into my definitions
