In science class, you learn that there are approximately 4.158 x 10^7 km^3—or 4.158 x 10^(19) L—of fresh water on Earth. You also learn that there are approximately 6.7 billion people living on Earth. According to a classmate, this works out to approximately 6.21 x 10^9 L of fresh water for each person on Earth.
Your classmate concludes that reports of water shortages in various parts of the world must be exaggerated.
Why is this an invalid conclusion? Support your answer by identifying at least two errors in your classmate's reasoning. Include any calculations that you used to arrive at your answer.

actually your concept is wrong

step-by-step explanation:

150% of x =300

150x=300×100

x=(300×100)÷150

x=200

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

where is the graph, sweetheart?

step-by-step explanation:

b. is true. hope this . happy
