D is correct. Hope this helped.
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.
It is a simple problem where 120 centimeters need to be increased by 24%. The increased length can be found by:
120 * (24/100)
= 12 * (24/10)
= 288/10
= 28.8 centimeters
Then the total length of increase = 28.8 cm
Then the increased length = (120 + 28.8) cm
= 148.8 cm
So the length becomes 148.8 cm after it is increased by 24%.
