Question 1098776: Kevin and Randy Muise have a jar containing 65;coins, all of which are either quarters or nickels. The total value of the coins in the jar is $12.25. How many of each type of coin do they have? Answer by ikleyn(52852) (Show Source):
Kevin and Randy Muise are so popular personages that I devoted the entire lesson to them
- Kevin and Randy Muise have a jar containing coins
Shortly speaking, you have this system of 2 equation
N + D = 65 (1) (counting) coins)
5N + 25Q = 1225 (2) (counting cents)
Or this single equation
4N + 25(65-N) = 1225.
Solve the system or the single equation, on your choice.
