Kevin and Randy Muise have a jar containing 80 coins, all of which are either quarters or nickels. The total value of the coins

SCORPION-xisa [38]

Answer:

39 quarters and 41 nickels

Step-by-step explanation:

Let the number of quarters be x and nickels be y.

Given:

Quarter is 25 cents
Nickel is 5 cents
Number of coins is 80
Total amount is $11.80 = 1180 cents

We have equations:

x + y = 80
25x + 5y = 1180

Solve the system by elimination, subtract 5 times the first equation from the second one:

25x + 5y - 5x - 5y = 1180 - 80*5
20x = 780
x = 780/20
x = 39

Find the value of y:

39 + y = 80
y = 80 - 39y = 41

Verify:

25*39 + 5*41 = 975 + 205 = 1180
