Answer:
There are 15,112 gallons of water will remaining in the pool ⇒ answer D
Step-by-step explanation:
* Lets explain how to solve the problem
- The rate is the ratio between two related quantities in different units
- The pool is leaking slowly at rate 9 gallons per second that means the
quantity of the water in the pool decreased 9 gallons each day
- The find the remaining gallons in the pool after 111 days, find the
amount of water has leaked from the pool in these days
∵ The rate of leaking is 9 gallons per day
∵ Mike does not replace the water that has leaked from the pool
- The amount of water leaked in some days = the rate of leaking
× the number of days
∵ The number of days is 111 days
∵ The amount of water lacked = 9 × 111 = 999 gallons
∵ The amount of water remaining in the pool after some days =
the total amount in the pool - the amount of leaked in that days
∵ The pool holds 16,111 gallons of water
∴ The amount of water remaining = 16111 - 999 = 15112 gallons
* There are 15,112 gallons of water will remaining in the pool
