n - 5
Step-by-step explanation:
We can represent any number as n:
Any number can be n. Now it is five less or:
-5
Creating an equation gives n - 5 as our answer.
Answer:
4x - 3
Step-by-step explanation:
(7x - 2) - (3x - 5)
Open the bracket and observe the signs,
7x -2 - 3x + 5 ( when the minus outside the bracket multiplies minus in the bracket, it becomes plus)
Collect like terms
7x - 3x - 2 + 5
4x - 3
Answer:

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)
