Minimum average cost = 743.75

Number of dvds to achieve the cost = 62.5

Step-by-step explanation:

Given the cost equation

C = 0.04x² − 5x + 900

To Obtian the minimum average cost ;

Find dc/dx = 0

Diffentiate cost, c it ith respect to x

dc/dx = 2(0.04x) - 5

dc/dx = 0.08x - 5 = 0

0.08x = 5

x = 5 / 0.08

x = 62.5

Substitute the value of x into C to obtain the minimum average cost

C = 0.04(62.5)² - 5(62.5) + 900

C = 743.75

2(t+1)=10. <br><br><br><br> need the answer for t I got the rest just can't get t
harkovskaia [24]

Answer: t=4

<u>Simplify both sides of the equation</u>

<u></u>(2)(t)+(2)(1)=10(Distribute)\\2t+2=10<u></u>

<u></u>

<u>Subtract 2 from both sides</u>

<u></u>2t+2-2=10-2\\2t=8<u></u>

<u></u>

<u>Divide both sides by 2</u>

<u></u>\frac{2t}{2} =\frac{8}{2} \\t=4<u></u>

I used 2/3 for tickits and 1/6 on popcorn how much money is left
posledela

Answer:

You would have 1/6 of your money remaining.

Step-by-step explanation:

Let's write an equation for this.

1 - (2/3 + 1/6)

First, let's multiply the numerator and denominator of 2/3. You get 4/6!

1 - (2/3 + 1/6)

1 - (4/6 + 1/6)

Next, let's add 4/6 and 1/6. You get 5/6!

1 - (4/6 + 1/6)

1 - 5/6

Finally, let's turn 1 into 6/6 and do 6/6 - 5/6!

1 - 5/6

6/6 - 5/6

1/6

You would have 1/6 of your money remaining.
