Answer:
125 %
Step-by-step explanation:
Computers purchased in the last month = 8
By the middle of the current month, 8 more computers than the last month were purchased. This means, total number of computers purchased by middle of current month = 8 + 8 = 16
Number of computers purchased by end of current month = 2
So,
Total computers purchased by current month = 16 + 2 = 18
We have to find the percentage increase in the number of computers from last month's purchases to the end of this month's purchases. The formula for percentage change is:
Here, Original Value is the number of computers from last month and New Value is the number of computers from current month. Using the values in the formula, we get:
Thus, there was a 125% increase from last month's purchases to the end of this month's purchases
