Question

Lemonade is drained at a constant rate of 8 fluid ounces per minute from a beverage dispenser containing 392 fluid ounces of lemonade. Which equation represents the number of fluid ounces of lemonade remaining in the dispenser, y , based on the number of minutes, t , since lemonade started draining from the beverage dispenser, where 0≤t≤49 ?

Answer 1

y = 392 - 8t

where y is the amount of lemonade remaining in ounces and t is the number of minutes since lemonade started draining.

We have the upper limit 0≤t≤49 because after 49 minutes the dispenser will be completely drained.
