Question

A man has 25 coins in his pocket, all of which are dimes and quarters. If the total value of his change is $3.55, how many dimes and how many quarters does he have?

Answer 1

Let x = the number of dimes and y = the number of quarters

 

x + y = 25                                              (25 coins in all)

($0.10)x + ($0.25)y = $3.55                    (Total value = $3.55)

 

Can you solve it from here?
