A colony of bees have produced about 4 oz of honey. Some time later they have about 7oz of honey. If the bees produce at a rate of 1.5% per hour, how many hours did it take?

It took 50 hours to produce 3 oz of honey.

Step-by-step explanation:

Rate of production = 1.5% per hour

Initial amount of honey = 4 oz

Final amount of honey = 7 oz

Honey produced = 3 oz

Amount produced = (initial amount x rate x time) / 100

3 = (4 x 1.5 x t) / 100

300 = 6t

t = 300/6

t = 50 hours

It took 50 hours for the bees to produce 3 oz of honey.
