==============================================
Work Shown:
The idea is that when we subtract 10x and x, the infinite decimal pattern (the 4s that go on forever) will cancel. That leads to 9x = 4 which solves to x = 4/9
Keywords:
<em>Cookies, boxes, sale, profit, unit cost </em>
For this case we have to bake an amount of 702 cookies, which were distributed in boxes of 18 for sale. Selling each box at the same price earned a profit of 136.50 dollars, you want to know the unit cost of each box of cookies.
Let be the number of boxes of cookies:
So, to know the number of boxes we divide 702 cookies among 18:
So, we have Tyler sold 39 boxes of cookies
Now, let be the cost of each box of cookies, to know the unit cost or sale price of the cookie boxes, we divided 136.50 dollars among 39 boxes of cookies, then:
Thus, the cost of each box was 3.5 dollars.
Answer:
The cost of a box is 3.5 dollars
