Tony paid $9.87 for 3 boxes of tissue.
how much did he pay for each box?
$ 3.29 is this right

To do this we will divide the amount he pays ($9.87) by the amount of boxes (3) he gets. Then the answer will be how much each box is for. lets do it:- 

9.87 ÷ 3 = 3.29
1 box of tissue cost $3.29.

CHECK OUR WORK:-

3.29 × 3 = 9.87
We were RIGHT!!

So, Tony pays $3.29 per box of tissue. (You were right!)
