Answer: 22 quarters
Step-by-step explanation:
Let N be the number of nickels.
Then the number of quarters is (55-N)
The nickels contribute 5N cents to the total.
The quarters contribute 25*(55-N) cents to the total.
5N + 25*(55-N) = 715
5N + 1375 - 25N = 715
-20N = 715 - 1375 = -660
So there is 22 quarters inside the jar.
Check to see if my answer is correct-
33*5 + 22*25 = 715 cents

Answer:
5.40
Step-by-step explanation:
Assuming w is the cost of one milk, let w =20
c = .25 (20) +.40
c = 5+.4
c =5.4
$92.50 * 10 =$925 ( deposited$92.50 into his account every month for 10 so we multiply)
$36.50*10 = $365 ( used $36.50 every month to pay art lessons every month means he took out)
925-365=560 ( total amt left in the account after taking out $365)
He used 1 over 2 of total money means
560/2 = 280
The answer would be B $280.
Hope this helps!!
