Question

A jar if dimes and quarters is worth $4.55. If there are the same number of dimes as quarters, what is the value of only the dimes?
PLEASE HELP

Answer 1

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 $
