Which situation results in a final value of zero ? (A) the overall change in temperature when the temperature goes from -10 F to 10 F (B)the total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars (C) the overall change in altitude of a hot air balloon after rising 21 kilometers from sea level (D) the total distance a person travels when he bikes 3.1 miles to school and then bikes 3.1 miles back home

(B)the total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars

Step-by-step explanation:

Let's analyse this using profit and loss formulas.

Profit = Cost price - selling price

In this case,:

Cost price = $2.25

Selling price is $2.25

Profit = ??

Let's invoke the formula:

Profit = Cost price - selling price

Profit = $2.25 - $2.25

Profit = $0

Therefore, the answer is (B)

The total profit made by a person buys an item for 2.25 dollars and then sells the item for 2.25 dollars
