Last year Jan had 25 model airplanes in her collection. This year she has 32% more model airplanes. Jan then gave her brother 6 model airplanes to start a collection. How many model airplanes does Jan have after she gave 6 to her brother?

Jan now has 27 model airplanes.

Step-by-step explanation: The starting figure is 25 model airplanes and this year she has 32% more than she started with. We shall first find out how many that turned out to be. Let the current number of model airplanes be X.

X = 25 + 32%

[To calculate 32% of 25

25 x 32/100

(25 x 32)/100

800/100

8]

X = 25 + 8

X = 33

Now she has 33 model airplanes and she gave out 6 of these to her brother, then she finally has left with her, 33 minus 6 which equals 27.

Jan now has 27 model airplanes left
