Answer:
63568 dollars
Step-by-step explanation:
Given that in your computer store you charge $1012 per computer sold. Your costs are given by the equation
![C(x) = 4x^2 + 4x - 80](https://tex.z-dn.net/?f=C%28x%29%20%3D%204x%5E2%20%2B%204x%20-%2080)
where x is the number of computers sold.
Revenue = sales price *no of computers sold
= 1012x
Profit = Revenue - cost
= ![1012x-( 4x^2 + 4x - 80)\\= 1008x-4x^2+80\\](https://tex.z-dn.net/?f=1012x-%28%204x%5E2%20%2B%204x%20-%2080%29%5C%5C%3D%201008x-4x%5E2%2B80%5C%5C)
Use derivative test to find maximum profit
![C'(x) = 1008-8x \\C''(x)= -x](https://tex.z-dn.net/?f=C%27%28x%29%20%3D%201008-8x%20%5C%5CC%27%27%28x%29%3D%20-x%3C0)
Equate I derivative to 0
x= 128
i.e. if 128 computers are manufactured and sold profit wouldbemaximum
Profit maximum=![1008(128)-4(128)^2+80\\=63568](https://tex.z-dn.net/?f=1008%28128%29-4%28128%29%5E2%2B80%5C%5C%3D63568)

Answer:
264
Step-by-step explanation:
do 20 mulitplyed by 30 then subtracted it by 336
Step-by-step explanation:
18p is a multiplication expression in itself.
It could be written as 18 x p. I am confused on what you mean as 'verbal' so i'm gonna take a wild guess and say word form.
eighteen times p???
Sorry if it's wrong.
Step 1. Divide both side by 16
100/16 = 6t - 13
Step 2. Dimplify 200/16 to 25/2
25/2 = 6t - 13
Step 3. Add 13 to both sides
25/2 + 13 = 6t
Step 4. Simplify 25/2 + 13 to 51/2
51/2 = 6t
Step 5. Divide both sides by 6
51/2/6 = t
Step 6. Simplify 51/2/6 to 51/2 * 6
51/2 * 6 = t
Step 7. Simplify 2 * 6 to 12
51/12 = t
Step 8. Simplify 51/12 to 17/4
17/4 = t
Step 9. Switch sides
t = 17/4
