Kent worked in the houseware section of a department store. This year he set a record high for vacuum sales with567 vacuum sold.

Gemiola [76]

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.
