Answer:
To break-even, Zorah needs to play for 8 hours.
Step-by-step explanation:
<u>To calculate the break-even point in hours, we need to use the following formula:</u>
Break-even point in units= fixed costs/ contribution margin per unit
Break-even point in units= 120 / (25 - 10)
Break-even point in units= 8 hours
To break-even, Zorah needs to play for 8 hours.
Answer:
(I don't know if this is correct)
To find the length of the rectangle, you need to first do 20 x 2 = 40 because when you finding the perimeter you have to do W + L + W + L = P (or Wx2 + Lx2 = P). You then subtract 40 from 68 (68 - 40) where you get 28 left. you then just divide 28/2 and you get 14. I may be way off but that's how I learned it.
