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.

$\text{Number of boxes of cookies}=\frac{702}{18}$

$\text{Number of boxes of cookies}=39$

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.

$\text{The cost of one box}=\frac{136.50}{39}$
