Question

The crew on a boat catch four fish that weigh a total of 240 pounds. The king mackerel weighs twice as much as the black fin tuna, and the wahoo weighs twice as much as the kind mackerel. The weight of the sailfish is 5 times as much as the black fin tuna. How much does each fish weight?

Answer 1

Answer:

f + 2f + 4f + 5f = 240lbs

Step-by-step explanation:

Black fin tuna (f): let f be the weight of the black fin tuna

King mackerel: 2(f)

Wahoo: 2(2(f))

Sailfish: 5(f)

so f + 2f + 4f + 5f = 240lbs

Hope this helps! :)
