Step-by-step explanation:
To calculate rate, divide the number of cans by the time to get "Cans per minute".
300/15min = 20/min
Let m represent minutes and c for cans.
We write an equation for the problem:
c = 20m
We want to know the time for 500 cans, so substitute 500 for c.
500 = 20m
Isolate m and solve:
m = 500/20
m = 25
It will take 25 minutes to put 500 labels.
