Answer:
4 1/5 gallons per minute
Step-by-step explanation:
Divide gallons by minutes.
(9 4/5 gal)/(2 1/3 min) = (49/5 gal)/(7/3 min) = (49/5)(3/7) gal/min
= 21/5 gal/min = 4 1/5 gal/min
First subtract the original high from the new high:
567 - 540 = 27 more vacuums sold.
Now divide the increase amount by the original high and multiply that by 100 to get the percentage:
27 / 540 = 0.05
0.05 * 100 = 5% Increase.
