She bought 8 pencils last month for 288, which is 36 cents each. And she bought 20 pencils this month for 720 which is 36 cents each. Hope this helped :)
It will cost 83.88 because there are 12 months in a year, and since it's $6.99 every month we will have to multiply $6.99 by 12 which would give us $83.88
