The correct option is A) 33.33%
Step-by-step explanation:
Consider the provided information.
Let the budget for the purchase of student computer was $100 over last year.
Now it increased 60% this year.
Therefore, the budget for the purchase of student computer is $160 in this year.
Let us assume that the cost of each computer was $1 over last year.
Now the cost increased by 20%.
Thus, the cost of each computer is $1.2 in this year.
The number of computer purchased in this year is:
Over the last year they can by 100 computers as the cost of each computer was $1 and budget was $100.
In this year they can by 133.33 computers as the cost of each computer is $1.2 and budget is $160.
That means they can by 33.33 more computers.
Hence, the number of computers it can purchase this year is 33.33% greater than the number of computers it purchased last year.
Therefore, the correct option is A) 33.33%
Note: You can assume any number for the cost of computer and budget the answer will remain same.
