Question

question 15 of 20 : select the best answer for the question. 15. a druggist is preparing a medication. each capsule requires 0.007 gram of aspirin. he has 14 grams of aspirin. how many capsules can he prepare? a. 500 b. 5,000 c. 200 d. 2,000 mark for review (will be highlighted on the review page)

Explanation:

Step1: Identify the formula

To find the number of capsules, divide the total amount of aspirin by the amount per capsule. Let $n$ be the number of capsules, $A_{total}$ be the total amount of aspirin and $A_{per - capsule}$ be the amount of aspirin per capsule. The formula is $n=\frac{A_{total}}{A_{per - capsule}}$.

Step2: Substitute the values

We know that $A_{total} = 14$ grams and $A_{per - capsule}=0.007$ grams. So $n=\frac{14}{0.007}$.

Step3: Calculate the result

$\frac{14}{0.007}=\frac{14}{\frac{7}{1000}}=14\times\frac{1000}{7}=2000$.

Answer:

D. 2,000
