24) A happy cat enjoys 9.5 to 19 ounces of milk for every 10 pounds of his weight. John has 15- and a 25-pound cats. Which of the following ranges represents the approximate total number of ounces of milk (m) that the two cats need to be happy?

1. 38<m<76
2. 29<m<48
3. 380<m<760
4. 760<m<1,520

You have about 40 pounds of cat in the word problem. For every 10 of those pounds, you have anywhere from 9.5 to 19 ounces. Multiply both times 4 and you get 38 and 76 ounces on the low and high ends, respectively. Therefore, Answer 1 is correct.
