A number was multiples by -4 then this product was increased by 4. If the result was -24 what was the number.
2 answers:
N = 7
(n * -4) + 4 = -24
-4 -4
Subtract 4 from both sides.
Now you should have
(n * -4) = -28
Now multiply n by -4 (you could've also done this before subtracting 4)
This should cause your equation to be
-4n = -28
Divide both sides by -4 in order to get n by itself (or make it equal 1)
n = 7
This is how I would do it atleast

Answer:
20%
Step-by-step explanation:
Profit = Income - cost
Profit = 10s - (28 + 3s) = 10s - 28 -3s = 7s - 28.
Profit = 0
0 = 7s - 28
7s = 28
7s = 28/7
s = 4. This is the breakeven point.
