Answer:

y = 10

Step-by-step explanation:

Given

10 - y = y - 10 ( subtract y from both sides )

loris [4]

Answer:

cost of a box is $3.5

Step-by-step explanation:

given data

sold box = 18

earned = $136.50

solution

we consider here number of boxes of cookies is x

and

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

Tyler sold = $\frac{702}{18}$

Tyler sold = 39 boxes

and

now we consider here y as cost of each box of cookies,

so for cost or sale price of the cookie boxes here we divided 136.50 dollars among 39 boxes

cost of each box = $\frac{136.5}{39}$

cost of each box = 3.5

Thus, the cost of each box was 3.5
