Anna hs 62 nickels and dimes. If the total value of her coins equals $4.45, how many nickels and dimes does she have?

The first thing we must do for this case is to denote variables.

We have then:

x = number of nickels

y = number of dimes

By writing the system of equations we have:

x + y = 62

0.05x + 0.10y = 4.45

Solving the system we have:

x = 35

y = 27

Answer:

She has:

nickels = 35

dimes = 27
