Answer:
Sam made 45 rolls
Step-by-step explanation:
After giving some to his neighbor, Sam has 1 -2/5 = 3/5 of the original quantity left. After giving some to his cousin, he has (3/5)(1 -4/9) = (3/5)(5/9) of the original quantity left.
(3/5)(5/9) = 3/9 = 1/3
15 rolls = (1/3)·(original number) . . . . . . Sam has 15 roll left
45 rolls = original number . . . . . . . . . . . multiply by 3
