A bookseller sells all his books at a profit of 10%. If he buys book from the distributor at $200, how much does he sell it for?

Step-by-step explanation:

CP of all his books = $200

profit = 10%

SP = CP ( 100 + gain% / 100 )

after inserting the values we got,

→ 200 ( 110/100 )

→ 2 × 110

→ 220

therefore, Selling Price of all the books are $220.

sorry i don't know the other answer. i didn't learn what a proportional relationship is.

step-by-step explanation:

let's assume

number of candles set =x

price of of x candles =p(x)

we are given

a candle maker prices one set of scented candles at $10 and sells an average of 200 sets each week

so, we get point as (200,10)

he finds that when he reduces the price by $1, he then sells 50 more candle sets each week

so, we can find slope

now, we can use point slope form of line

now, we can plug values

we can use point

and find b

now, we can plug it back

and we get

now, we can find revenue

we know that

revenue = price*quantity

so, we get
