<h3>What is the equation that represents the cost of the gym membership?</h3>
The cost of gym membership is the sum of the fixed cost and the variable cost. The fixed cost is the start-up fee while the variable cost is the cost per month.
The equation that represents the cost of the gym membership is: c = $100 + $40m
Where m represents the number of months
The cost of 1 year membership = $100 + $40(12)
$100 + $480 = $580
How many months would $460 cover = ($460 - $100) / 40 = 9 months

Answer:
12 minutes
Step-by-step explanation:
The volume of the aquarium is ...
V = LWH
V = (25 in)(19 in)(12 in) = 5700 in³
The time required to empty it is given by ...
time = quantity/rate
time = (5700 in³)/(475 in³/min) = 12 min
It takes 12 minutes to empty the aquarium.
