The number of computers increased by 38.9%

Step-by-step explanation:

Number of computers at start of week = Old value = 18

Number of computers by end of week = New value = 25

Change = New value - Old value

Change = 25-18 = +7

The positive sign indicates the increase.

Increase percent = \frac{Change}{Old\ value}*100

Increase\ percent=\frac{7}{18}*100\\\\Increase\ percent=\frac{700}{18}\\\\Increase\ percent= 38.88\%

Rounding off to nearest tenth

Increase percent = 38.9%

The number of computers increased by 38.9%

Keywords: difference, percentage
