20/8 and 45/18

Step-by-step explanation:

Set each fraction up with the proportion 10/4 and cross multiply to see if there products are equal.

10/4=45/18

10×18=180 45×4=180

180=180

number of candles set =x

price of of x candles =p(x)

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
