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?
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*6 = 12 pounds
Frances’s towels weigh a total of 12*16 = 192 ounces
