Answer:
your profit is Double the price that you bought the kits
Step-by-step explanation:
x= cost of kit
you buy it x/2
x/2 + 4.5 .... (1)
x + x/2 +4.5 .... (2)
let x = 40
40/2 + 4.5 = 24.5
40 + 40/2 + 4.5 = 64.5
64.5 - 24.5 = 40
so
you buy it in x/2 = 40/2 = 20
and sell it in x = 40
40/20 = 2
your profit is Double the price that you bought the kits
It’s extremely blurry and hard to see. But if I’m correct it looks like this:
3(x+1)
7(x+4)
We can solve these problems by simplifying.
The first answer is: 3x+3
The second answer is: 7x+28
I’m not completely sure that you wanted those simplified, but that’s how I did it. If you need it calculated differently, please let me know!
