An ad on tv claims that 70% of doctors interviewed chose brady's aspirin as the leading medicine to cure minor aches. if 20 doctors were interviewed, how many chose brady's?
Answer:
14 doctors choose Brady's.
Step-by-step explanation:
Given,
Total number of doctors that were interviewed = 20,
Also, 70% of doctors interviewed chose brady's aspirin,
Thus, the numbers of the doctors who choose Brady's = 70 % of 20
\(=\frac{70}{100}\times 20\)
\(=\frac{1400}{100}\)
\(=14\)
