Question 891848: Suppose you have 65 coins in a jar consisting entirely of nickels and quarters, worth a total of $9.25. How many nickels are in the jar? Type in your numerical answer only; do not type any words or letters with your answer.
Answer by JulietG(1812)   (Show Source):
You can put this solution on YOUR website! If all the coins were quarters, you would have 65 * .25, or $16.25
Your actual total is $9.25. $16.25 - $9.25 = $7.00
The difference between a quarter and a nickel is .20
7.00 / .20 = 35
You have 35 nickels.
If you have 65 coins, and 35 are nickels, you have 30 quarters.
35 nickels @ .05 = $1.75
30 quarters @ .25 = $7.50
$7.50 + $1.75 = $9.25
Success!
