Step-by-step explanation:
The break even point is when the revenue is equal to the cost.
Revenue:
How much the store earns for each shirt.
We want to find the price of each shirt, and 50 shirts will be made.
So the revenue function is:

In which p is the price.
Costs:
A clothing store spends $10 for each shirt it produces and has fixed costs of $400.

400 + 50*10 = 900
Breakeven
Revenue equals cost
50p = 900
p = 900/50
p = 18
So the correct answer is:
b)$18
Answer:
x ∈ (-∞,-3)∪(0.5,∞)
Step-by-step explanation:
2x^2+6x-x-3>0
2x(x+3)-1(x+3)>0
(2x-1)(x+3)>0
x ∈ (-∞,-3)∪(0.5,∞)
