Answer:
Total amount of water in cooler = 144 ounce
Amount of water used to fill his bottle = 16 ounce
Amount of water filled in single plastic cup = x ounce
Total number of cups = 16
The equation for the given information is
⇒ 16 + 16 x=144
⇒16 x=144- 16
⇒ 16 x=128
⇒ x= 128÷16
⇒ x=8
Amount of water in each cup= 8
It is not mentioned that after filling 16 plastic cups is there water left in cooler.
If water is left in cooler after filling 16 plastic cups, suppose it's volume is y -ounce.
Then the equation becomes
⇒144=16 +16 x + y
⇒ 16 x + y =144-16
⇒16 x + y =128
So it is equation in two variables , so for different amount of water left in cooler(y), there will be be different ounces of water in plastic cups(x).
