Question

According to the U.S. Census Bureau, in 1950, 39.3 million families had a child under 18 at home. Suppose a recent study found that number had decreased by 9.3%. How many million families had a child under 18 at home according to this study? Round the number of millions to the nearest tenth.

Answer 1

Answer: 35.7 million

Explanation:

Number of families that have a child of under 18 at home = 39,300,000

Percentage decrease = 9.3% = 0.093

The number of families that had a child under 18 at home according to this study will be:

= 39.3 million - (39.3 million × 0.093)

= 39.3 million - 3.6549 million

= 35.6451 million

= 35.7 million
