The sum of the angles equals 540

There are 3 angles that measure (x - 30) and 2 angles that measure (x)

3(x - 30) + 2(x) = 540

3x - 90 + 2x = 540

5x - 90 = 540

5x = 630

x = 126

x - 30   = 126 - 30   = 96

Answer: x = 126,  x-30 = 96

pav-90 [236]

Answer: You receive 14x+45 dollars for each gallon of cider that you sell.

Step-by-step explanation:

Given: For selling each gallon of cider, the company receives x dollars.

i.e. You receive  $(Selling price - x)

By selling 15 gallons in 15x+45 dollars, you have received (15x+45)-x dollars

i.e. You received 15x+45-x dollars

i.e. You received 14x+45 dollars.

Hence,  you receive 14x+45 dollars for each gallon of cider that you sell.
