You have to find out what 15% of $78 dollars is. If you have to do this in your head and not on a calculator you can find 10%, then cut that number in 1/2 and add it to the answer. So 10% of $78 is 7.8 so $7.80. You can divide 7.80 by 2 and get 3.9 and add that to 7.8 which is 11.70. So 15% of $78 is $11.70.

First we would need to find the portion of the gymnasium to the blueprint to do that please do this:
88/5.5 = 16
The length divided by the blueprint's length
Since we know that the gymnasium is 16 times the blueprint, to find the width divide 16 to 76:
76/16 = 4.75
The width divided by the 16 times
The width of the blueprint is 4.75 inches
