The equation C = 30x+120 represents the cost of producing gaming chairs. The equation R = 50x represents the revenue generated b
ANEK [815]

Answer:

6 chairs

Step-by-step explanation:

The break even Point on gaming chairs can be expressed as :

Revenue = Cost

Revenue, R = 50x

Cost, C = 30x + 120

R = C

50x = 30x + 120

50 - 30x = 120

20x = 120

Divide both sides by 20

20x/ 20 = 120 / 20

x = 6

Hence, 6 chairs must be sold for the company to break even.

What is four hundred twenty times six
lianna [129]
To do this without a calculator, it may be easier to break the number into smaller parts.

= 2400 + 120
= 2520

Hope this helps! :)

Answer:

Qu. 8 = A (50) = 25w  as 125w x 125l = Area ; this because perimeter 500ft would always be a 3:5 ratio to the larger area. Therefore perimeter is 125+125 +125 +125 and = 500ft. However we can prove if 125 is any length or width then A(50)= 1/5 = 25   Qu 9)= I think last 2 are a function. Qu 10) Answer B is correct.
