A manufacturer of an anti-inflammatory drug claims that the drug will be effective for 6 hours. An independent testing service determined that the drug was effective for only 80% of the length of time claimed by the manufacturer. Find the length of time the drug will be effective as determined by the testing service.
.8 * 6 = 4.8
To find the length of time the drug will be effective as determined by the testing service, we need to calculate 80% of the claimed effectiveness of 6 hours.
To do this, multiply 80% (or 0.80) by 6 hours:
0.80 * 6 = 4.8
Therefore, the drug will be effective for approximately 4.8 hours as determined by the testing service.
