percent did he make?
(Ans=17%) I WANT PROCESS!​

Answer 1

I am thinking answer is 20 percent

Step-by-step explanation:

30 -20=10

Answer 2

Step-by-step explanation:

let x be the price of the radio

so profit = x +(30% of x) = x+ 30x/100 = 130x/100

Now discount = 10%

So it is to be subtracted from the profit that he is making

• 130x/100 - (10%of 130x/100 )

= 130x/100-(10/100 × 130x/100)

= 130x/100 - 13x/100

= 117x/100 = x + 17x/100

where x is the cost price and 17x/100 or 17% of x is the profit .

(note: just an example)

lets say the marked price is 50=x

= 117×50/100 = 58.5

here total price with profit is 58.5 and 8.5 is the profit price = 17%
