Answer:
B. 7
Explanation:
To find this out, first, we multiply 89*2, which is 178, the amount already spent on toner.
Then, we add 27 to this to find the total amount spent so far. This comes out to $205 spent so far.
To find out how much we have left to spend, we subtract the amount spent from the original.
400-205 = $195, the amount of money left.
To find out how much paper we can buy, we divide the cost of one paper box, by the amount of money we have left.
195/27 = 7.222222222222222222222222222222
Since we cannot buy 7.222222222222222222222222 boxes, we can only buy 7. This is the answer.
