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)

Answer:
it will take her 90000 seconds to complete 3000 piece of puzzle
Step-by-step explanation:
every 30 seconds, a correct puzzle piece , meaning 1 piece
how long would it take her to complete a 3000 piece puzzle
so let x = how long it would take her to complete a 3000 piece puzzle
so if 30 seconds = 1 piece
x seconds = 3000 piece
x = 90000 seconds
Answer:
x= 29
Step-by-step explanation:
These angles equal 180° since they are corresponding angles.
So, the equation would be: (2x-10)+(4x+16)= 180.
Step 1- Add common variables.
(2x+4x)+(16-10)= 180
6x+6= 180
Step 2- Subtract 6 to both sides.
6x+6= 180
-6 -6
6x= 174
Step 3- Divide both sides by 6.
<u>6x</u>= <u>174</u>
6 6
x= 29
