quarters that he has?
a) 25n +59 = 365
29-4=n

49 +2=n
c) 5n + 256 = 365
29-4=

Answer:

c) 5n +25q = 365

2q -4 = n

Explanation:

The number of nickels (n) is 4 less than twice the number of quarters (q), so one of the equations is ...

2q -4 = n

The face value is 365 cents, so another equation is ...

5n +25q = 365

These equations seem to match choice C.
