Answer:
let cp be x
mp= x+ (20% 0f x)= 1.2x
sp = mp -d%of mp= 1.2- 15% *1.2 =1.02x
profit = 40
sp-cp =40
1.02x-x=40
x=2000
cp =2000
mp= 1.2*2000=2400
Step-by-step explanation:
Answer:
c/8
Step-by-step explanation:
This is division. This can be figured out by reading "split". If something is to be split, it is the dividend.

Answer:
a = any positive multiple of 3
Step-by-step explanation:
You want ...
(5 1/3)/(4/a) = whole number
(16/3)·(a/4) = whole number
(4a/3) = whole number
This will be the case for a = 3n, for any positive integer n.
Answer:
a= 2x <u><em>(edit: i just forgot it should be a integer x.x, forgive my blondiness)</em></u>
Step-by-step explanation:
usually when doing equations like that, you can separate one of the parenthesis with 0
(in this case, we will use (2x-a) )
Then create a equation, which should look like:
2x-a=0
Then solve for a
