Mary just arrived at the beach. She has 4 times as many towels as Frances does. The total weight of their towels is 60 pounds. If Mary has 24 towels, how much do Frances's towels weigh in ounces?
Step-by-step reasoning:
128
Frances has 24 / 4 = 6 towels.

They have 24 + 6 = 30 towels.

Each towel weighs 60 / 30 = 2 pounds.

Frances’s towels weigh a total of 2 * 4 = 8 pounds.

Frances’s towels weigh a total of 8 * 16 = 128 ounces.

.

Therefore, the answer is 128
