China's area is about 3.7 million square miles. It is on the continent of Asia, which has an area of about 17.2 million square miles. About what percent of the Asian continent does China cover? A. About 10 B. About 15 C. About 17 D. About 22? (I need to know how to solve it as well if possible.)

The answer to your question is the letter D.About 22

Step-by-step explanation:

Data

China's area = 3 700000 mi²

Asia's area = 17 200000 mi²

Process

1.- Consider the Asia's area as 100% and use proportions to solve this problem

                   17 200000 100 mi²

                    3 700000  x

                    x = (3700000 x 100) / 17200000

- Simplification

                    x = 370000000 / 17200000

-Result

                    x = 21.51 ≈ 22                      

about 168 miles

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
