Question
Jim has 44 nickels & dimes totaling $2.95. How many nickels does he have?
Expert Solution
Step 1
Let's assume that Jim has x nickels and y dimes.
We know that he has a total of 44 coins, so:
x + y = 44
We also know that the total value of the coins is $2.95,
1 nickel = 0.05 dollar
1 dime = 0.10 dollar
which can be expressed in cents as:
5x + 10y = 295
x + 2y = 59
