Answer:

$90 (assuming 1 book per camper)

Step-by-step explanation:

We are not told the number of books per camper.

If each camper gets 1 book, then since there are 12 campers, then there are 12 books.

12 * $7.50 = $90

(BTW, the word "spended" does not exist. The correct word is "spent.")

Find x- and y-intercepts. Write ordered pairs representing the points where the line crosses the axes. y−3x=18
Radda [10]

Answer:

see explanation

Step-by-step explanation:

Given

y - 3x = 18

To find the y- intercept let x = 0 in the equation and solve for y

y - 3(0) = 18

y - 0 = 18

y = 18 ⇒ (0,18 ) ← y - intercept

To find the x- intercept let y = 0 in the equation and solve for x

0 - 3x = 18

- 3x = 18  ( divide both sides by - 3 )

x = - 6 ⇒ (- 6, 0 ) ← x- intercept

Suppose that the dollar cost of producing x radios is c(x) = 400 + 20x - 0.2x 2. Find the marginal cost when 30 radios are produ
My name is Ann [436]
C(x) = 400 + 20x - 0.2x²

c(30) = 400 + 20(30) - 0.2(30)²

= 400 + 600 - 0.2(900)
= 1000 - 180
= 820

It costs $820 when 30 radios are produced. 

Marginal cost is how much it would cost to make one MORE of the same product so now we find how much it costs to produce 31 radios and compare the two. 

c(31) = 400 + 20(31) - 0.2(31)²

= 400 + 620 - 0.2(961)
= 1020 - 192.2
= 827.8 or ≈828.

Now we find the difference which means we subtract the two. 

828 - 820 = 8. 

Your marginal cost is $8. 

To compare we can also do 29 radios. 

c(29) = 400 + 20(29) - 0.2(29)² = 811.8 or ≈812

820 - 812 = 8.
