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:

Cookies, boxes, sale, profit, unit cost

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

Jimmy decides to mow lawns to earn money. The initial cost of his electric lawnmower is $350. Electricity and maintenance costs

hodyreva [135]

Answer:

a) C(x) = 4x + 350

b) 13x; $13

c) 39

Step-by-step explanation:

a) Initial cost of lawnmower = $350

Maintenance cost for 1 lawn = $4

Maintenance cost for x lawns = 4x

Total cost function, C(x) = 4x + 350

b) Revenue = Cost + Profit

= C(x) + P(x)

= 4x + 350 + 9x - 350

= 13x

Charge per lawn = $\frac{\text{Revenue}}{\text{Number of lawns}}$

= $\frac{13x}{13} = \$13$

c) For Jimmy to make a profit, P(x) must be greater than zero i.e.

$P(x) >0$

$9x-350 >0$

$9x >350$

The smallest integer value of x that satisfies this inequality is 39. Therefore, Jimmy needs to mow 39 lawns in order to start making profit.

What is the area of the playground? (Look at the picture provided)

Pachacha [2.7K]

64+36+30+80= 210 yards sq, because you break up the playground into squares and rectangles then multiply the with times length. For the slanted part, you create it into a square and use the yd from the other sides of the playground.
