For this case, the first thing we must do is define variables. We have then: x = number of dimes y = number of quarters We write the system of equations: 0.10x + 0.25y = 4.55 x = y Solving the system we have: x = 13 y = 13 The value of the dimes is: (0.10) * (13) = 1.3 $ Answer: The value of only the dimes is: 1.3 $
