The number of rows will be a divisor of 550 such that the quotient is 3 more.
... 550 = 1×550 = 2×275 ≈ 5×110 = 10×55 = 11×50 = 22×25
Factors 22 and 25 differ by 3.

Answer:
d = 13 and n = 52
Step-by-step explanation:
Number of dimes: d
Number of nickels: n
Then d + n = 65, and n = 4d
Substituting 4d for n in the first equation, we get:
d + 4d = 65, or 5d = 65. Then d = 13 and n = 52
