Step-by-step explanation:
Answer:
n = 150
Step-by-step explanation:
If n is the number of T-shirt sell each month, then the revenue function of Sophia's store is r = 21n .......... (1)
and the cost function of her store is C = 16n + 750 ........ (2)
Now, at break-even point, the revenue of a business is equal to its cost.
Therefore, r = C
{From equations (1) and (2)}
⇒ 21n = 16n + 750
⇒ 5n = 750
⇒ n = 150
So, the break-even point of the store will occur when the number of T-shirt production is 150. (Answer)
Answer:
y = 3.3x + 20
Step-by-step explanation:
-2/3x +1/5y = 4 y = mx + b
-2/3x + 1/5y = 4
-2/3 -2/3
1/5y = 2/3 + 4
1/5 / 2/3 = 3.3
1/5 / 4 = 20
y = 3.3x + 20
