Q. Bob's Gift Shop sold

200

cards for Mother's Day. One salesman, Jacob, sold

10 \%

of the cards sold for Mother's Day. How many cards did Jacob sell?

\newline

Answer:

Calculate $10$ % of Total Cards: To find out how many cards Jacob sold, we need to calculate $10\%$ of the total cards sold for Mother's Day. Since the total number of cards sold is $200$ , we need to find $10\%$ of $200$ . $\newline$ Calculation: $10\%$ of $200 = (\frac{10}{100}) \times 200$
Perform Multiplication: Now we perform the multiplication to find the number of cards Jacob sold. $\newline$ Calculation: $(\frac{10}{100}) \times 200 = 0.10 \times 200 = 20$
Final Answer and Checking: We have calculated that Jacob sold $20$ cards. This is the final answer, and we should check it to ensure there are no mathematical errors. $\newline$ Checking: $10\%$ of $200$ is indeed $20$ , which means the calculation is correct.

Question

Alice studies the relationship between climate and heart disease around the world.

\newline

H(t)

models the probability for the occurrence of heart disease (in percents relative to the global average) at an area where the temperature is

t

degrees Celsius.

\newline

According to Alice's model, when the temperature is

-5^{\circ}C

(which is the lowest temperature included in the model), the probability is

10\%

above average. Then the probability decreases until the temperature reaches

30^{\circ}C

(which is the highest temperature included in the model), where the probability is

20\%
