Tyler baked 702 cookies. He sold them in boxes of 1i. After selling all the boxes of cookies for the same amount each he earned

ikadub [295]

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.

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

$\text{The cost of one box}=3.5$

Therefore, the cost of one box of cookies is $3.5.

Step-by-step explanation:

We know that the washer costs $51 more dollars than the dryer.

The washer costs x+51

The dryer costs x

2x=900

x=450

Amayo943,

Remember that with exponents you have to multiply the number of exponets by the same number it's in for example: $1^2 = 1 \times 1$ In this case you need to know that:

$15^2 = 15 \times 15$
$15 \times 15 = 225$
$=225$

Therefore your answer is "225."

Hope this helps!
