John has three more dimes than nickels in his pocket, for a total of $2.65. Which equation could be used to
determine the number of dimes, x, in his pocket?
Which equation below represents the relationship between
the coins and the total value?
0.10(x+3)+0.05(x) = 2.65
0.05(x + 3) +0.10(x) = 2.65
0.10(3x)+ 0.05(x) = 2.65
• 0.05(3x)+0.10(x) = 2.65
