Tyler baked 702 cookies he sold them in boxes of 18 after selling all of the boxes of cookies for the same amount of each he ear
jenyasd209 [6]

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 "x"be the number of boxes of cookies:

So, to know the number of boxes we divide 702 cookies among 18:

x = \frac {702} {18}\\x = 39

So, we have Tyler sold 39 boxes of cookies

Now, let "y" 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:

y = \frac {136.50} {39}\\y = 3.5

Thus, the cost of each box was 3.5 dollars.

Answer:

The cost of a box is 3.5 dollars

Find the difference.<br><br> Show your work<br><br> -3/4 - 4/3
myrzilka [38]

Answer:

-25/12

Step-by-step explanation:

I assume you want to subtract 4/3 from -3/4   OR   combine -3/4 and -4/3.

Here the LCD is (4)(3) = 12.

Then -3/4 becomes -9/12 and -4/3 becomes -16/12.  

Then -9/12 - 16/12 = -25/12
