Find the Average Rate of Change Illustrated in the Graph $\frac { 1 } { 4 }$

Find the average rate of change illustrated in the graph.
-A faucet is used to add water to a large bottle that already contained some water. After it has been filling for 5 seconds, the gauge on the bottle indicates that it contains 25 ounces of water. After it has been filling for 12
Seconds, the gauge indicates the bottle contains 53 ounces of water. Find and interpret the average rate of
Change in the volume of water per second.

A) $\frac { 1 } { 4 }$ ounce per second; the average rate of change in the volume of water is $\frac { 1 } { 4 }$ ounce per second.
B) 41 ounces per second; the average rate of change in the volume of water is 41 ounces per second.
C) 4 ounces per second; the average rate of change in the volume of water is 4 ounces per second.
D) 5 ounces per second; the average rate of change in the volume of water is 5 ounces per second.
