Kevin and Randy Muise have a jar containing 4444 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $nbsp 7.20 7.20. How many of each type of coin do they have?

they have 25 quarters and 19 nickels

Explanation:

let N = number of nickels

let Q = number of quarters

5N + 25Q = 720

N + Q = 44

N = 44 - Q (now we must replace)

5 (44 - Q) + 25Q = 720

220 - 5Q + 25Q = 720

20Q = 720 - 220 = 500

Q = 500 / 20 = 25

N = 44 - 25 = 19
