Q. In which story is the answer to the question

0

?

\newline

Choices:

\newline

(A)When Liz climbed Mount Rainier, the windchill temperature was

-4^\circ\text{C}

. The actual temperature outside was

4^\circ\text{C}

warmer than the windchill temperature. What was the actual temperature outside?

\newline

(B)When Liz climbed Mount Rainier, the windchill temperature was

-4^\circ\text{C}

. The actual temperature outside was

4^\circ\text{C}

. How much warmer was the actual temperature outside than the windchill temperature?

Solve for Actual Temperature: Step $1$ : Solve for the actual temperature outside in story (A). The windchill temperature is given as $-4^\circ\text{C}$ , and it's stated that the actual temperature is $4^\circ\text{C}$ warmer than the windchill. Calculation: $-4^\circ\text{C} + 4^\circ\text{C} = 0^\circ\text{C}$ .
Solve for Temperature Difference: Step $2$ : Solve for the difference in temperature in story (B). The windchill temperature is $-4^\circ\text{C}$ , and the actual temperature outside is given as $4^\circ\text{C}$ . Calculation: $4^\circ\text{C} - (-4^\circ\text{C}) = 8^\circ\text{C}$ .
Determine Correct Answer: Step $3$ : Determine which story's question results in an answer of $0$ . From Step $1$ , the actual temperature outside in story (A) is $0^\circ\text{C}$ . In story (B), the difference in temperature is $8^\circ\text{C}$ .

Question

\$ 200

with which to purchase hats and t-shirts that are to be sold at his class' next fundraiser. Each hat costs the same amount of money, and each t-shirt costs the same amount of money. If Aiden spends all his money entirely on hats, he will get
