lukranit [14]

the bottom of the pool is 15 x 30 = 450 sq feet.

 you the have 2 walls that are 30 x 5 = 150 x 2 = 300 square feet

 then 2 walls that are 15 x 5 = 75 x 2 = 150 square feet

 for a total of 450 +300 +150 = 900 square feet

 1 can covers 250 sq ft

so 900/250 = 3.6

 so you would need 4 cans of paint

PSYCHO15rus [73]

Answer:

Step-by-step explanation:

If the company wants to just break even, that means that the cost to produce 150 guitars is equal to the price they charge to make a 0 profit. The cost of 150 guitars is

C(150) = 100(150) + 56000 and

C(150) = 71000. That's how much it costs to produce 150 guitars. If they want to make nothing at all, they have to sell the 150 guitars for

p(x) = 71000/150 so

p(x) = 473.33 or 474
