Aschool’s annual budget for the purchase of student computers increased by 60% this year over last year. if the price of student computers increased by 20% this year, then the number of computers it can purchase this year is what percent greater than the number of computers it purchased last year? a. 33.33%b. 40%c. 42%d. 48%e. 60%

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.

the first one is x^2+2x+2

the second one is x^2+4

the last one is x^2-4x+8

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
