Answer:

see below

Step-by-step explanation:

A percentage change is computed as follows:

percent change = ((new value) -(original value))/(original value) × 100%

For your first one, this looks like ...

percent change = ($25 -$75)/$75 × 100% = (-50/75) × 100% = -0.667×100%

percent change = -66.7%

When there are a lot of similar calculations to do, I like to use a spreadsheet. See below for the other percentage changes (rightmost column).

A camera manufacturer spends $2,000 each day for overhead expenses plus $9 per camera for labor and materials. The cameras sell

hjlf

A) let the number of cameras sold per day for breakeven be x

Total daily cost = 2000 + 9x

Total daily revenue = 17x

therefore for just covering expenses both cost and revenue must be equal

2000 + 9x = 17x

2000 = 17x - 9x = 8x

x = 2000/8 = 250 cameras

b) increasing production by 50 cameras per day will give a daily profit of;

50 * (17 - 9) = 50 * 8 = $400 (seeing that the fixed daily cost of $2000 remains unchanged)

A line passes through the point (2, 3) and has an undefined slope, what is the equation of the line? A) y = 2 B) y = 3 C) x = 2

Harman [31]

"Undefined" slope means the line is vertical, of the form x = constant. The constant is the x-value of the point the line goes through.

C) x = 2

What is the solution to the system of equations? {2x+5y=3y=x+2 (1, 3) (−1, 3) (17, 157) (−1, 1)

In-s [12.5K]

Answer:

Step-by-step explanation:

2x + 5y = 3

y = x + 2

2x + 5(x + 2) = 3

2x + 5x + 10 = 3

7x + 10 = 3

7x = -7

x = -1

y = -1 + 2

y = 1
