Acamera manufacturer spends $1,800 each day for overhead expenses plus $9 per camera for labor and materials. the cameras sell for $18 each.
a. how many cameras must the company sell in one day to equal its daily costs?
b. if the manufacturer can increase production by 50 cameras per day, what would their daily profit be?
a. 200; $900
b. 200; $450
c. 150; $0
d.100; $450

We let x be the number of cameras that need to be sold. The total cost for manufacturing x cameras is,
                            9x + 1800
a. To equal its daily cost, the equation would be
                     9x + 1800 = 18x
The value of x from the equation is 200. 

b. For 250 cameras sold,
                      18(250) - ((9)(250) + 1800) = 450

Therefore, the answer is letter B.  

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
