A soap maker manufactures bars of soap in three different sizes: 3. 15-ounce, 4-ounce, and 6-ounce bars. The company randomly surveyed people at a number of supermarkets across the country about which size bar they typically buy. Survey results showed that 40% buy the 3. 15-ounce bar, 50% prefer the 4-ounce bar, and 10% purchase the 6-ounce bar. If the company sells 62,500 bars of soap each day, approximately how many 3. 15-ounce bars should they sell per day across the country?.
