Question

Andrew has 8.85 in dimes and quarters. The number of dimes he has is 3 more than twice his number of quarters. How many quarters does Andrew have?

Answer 1

$8.85 = d + q
          = (2q+3)+q                       d = dimes;  q = quarters
          = 4q+3
8.85 -3= 4q+3 -3
    5.85 =4q
  5.85/4=4q/4
        1.47=q
