How can you solve for x in the proportion 7/8 = x/24 a. set the sum of 7 and 8 equal to the sum of 24 and x, and then solve for x. b. set the sum of 7 and 24 equal to the sum of 8 and x, and then solve for x. c. set the product of 7 and 8 equal to the product of 24 and x, and then solve for x. d. set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

Step-by-step explanation:

We have to determine how we can solve for x in the proportion:

7/8=x/24

Multiplying both sides by 8×24,we get

i.e. 7×24=x×8

As we can see, we have to set the product of 7 and 24 equal to the product of 8 and x and then solve for x

Hence, Correct option is:

D. Set the product of 7 and 24 equal to the product of 8 and x, and then solve for x.

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
