Question

The zookeeper in charge of the seal exhibit has received her order of water chemicals. She will use these items to help keep the water in the seal exhibit healthy for the animals. She has received 150 ounces of chlorine. If she applies 15/2 ounces of this chemical to the water every 3 days, how long will this supply last?

Answer 1

To calculate how long the supply of chlorine will last, we can divide the total amount of chlorine (150 ounces) by the amount used per application (15/2 ounces) and then multiply by the frequency of application (every 3 days).

150 ounces ÷ (15/2 ounces) × 3 days = 150 ounces ÷ (7.5 ounces) × 3 days = 20 × 3 = 60 days.

Therefore, the supply of chlorine will last for approximately 60 days.
