Answer:
Jonathan has a jar filled with Nicholas dollars in quarters he has 57 coins in total and the value of those coins is $6.50 if he has 20 knuckles how many dollars in quarters does he have
Explanation:
Number of Nickels = n
Number of Quarters = k
n + k = 57
5n + 25k = 650
If n = 20
k = 57 - n
k = 57 - 20
k = 37
