Answer:
$3.5
Step-by-step explanation:
We have been given that Tyler baked 702 cookies. He sold them in boxes of 18.
First of all we will find the number of boxes of cookies by dividing 702 by 18.


We are told that after selling all the boxes of cookies for the same amount each he earned $136.50. To find the cost of each box we will divide 136.50 by 39.


Therefore, the cost of one box of cookies is $3.5.
Pretty much trade. You give vendor money or currency in return they give you the thing you paid for.

![\rule[225]{225}{2}](https://tex.z-dn.net/?f=%5Crule%5B225%5D%7B225%7D%7B2%7D)
If you have to estimate I will put $85 and then to find 20 % you just have to kniw that 10% is equal to 8.5 you just move a decimal then you just add 8.5 plus 8.5 = 17 so 20% of 85 is equal to $17 and to find 15% you already know how much is 10%=8.5 so you just need to find 5% that is equal to 4.25 and then you just add 4.25 to 8.5 and that's equal to 12.75
20%= 17
15%=12.5
