Answer:
cost of a box is $3.5
Step-by-step explanation:
given data
sold box = 18
earned = $136.50
solution

and
for we get Tyler sold cookies box so number of boxes we divide 702 cookies among 18 is
Tyler sold =
Tyler sold = 39 boxes
and

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes
so
cost of each box =
cost of each box = 3.5
Thus, the cost of each box was 3.5
