AHow many of the 3005 subjects used at least one prescription medication?

Verified Answer :

Multiply 3005 by 0.817 to get your answer, because that will give you 81.7% of 3005, and the number of subjects who used at least one prescription medication.

Answer:

2455 subjects.

Step-by-step explanation:

In a survey the total number of people aged 57 to 85 years = 3005

The percentage of the people those used at least one prescription medication = 81.7%

The number of the subjects used at least one prescription medication

= 81.7% of 3005

= \(\frac{81.7}{100}\times 3005\)

= 0.817 × 3005

= 2455.085 ≈ 2455 subjects.

2455 subjects used at least one prescription medication.
