48 oz
67 oz
clear my selection

Explanation:

Step1: Recall pounds to ounces conversion

1 pound = 16 ounces. So, 3 pounds in ounces is $3\times16 = 48$ ounces.

Step2: Add the existing ounces

David has 3 pounds (48 ounces) and 9 ounces. So total ounces is $48 + 9 = 57$ ounces? Wait, no, wait—wait, maybe I misread. Wait, the problem says "David has 3 pounds and 9 ounces of dog food. How many ounces of dog food does he have?" Wait, 1 pound is 16 ounces, so 3 pounds is $3\times16 = 48$ ounces. Then add 9 ounces: $48 + 9 = 57$ ounces? But the options are 39 oz, 40 oz, 48 oz, 57 oz. Wait, maybe the original problem was 3 pounds and 9 ounces? Wait, no—wait, maybe I made a mistake. Wait, 3 pounds is 48 ounces? No, 1 pound is 16 ounces, so 3 pounds is 316=48? Wait, no, 163=48? Wait, 163 is 48? Wait, 103=30, 63=18, 30+18=48. Then 48 + 9=57. So the correct answer should be 57 oz. Wait, but the options: let's check the image again. The options are 39 oz, 40 oz, 48 oz, 57 oz. So the correct one is 57 oz. Wait, but maybe the problem was 3 pounds minus 9 ounces? No, the question is "how many ounces does he have" with 3 pounds and 9 ounces. So 316 +9=48+9=57. So the correct option is the last one, 57 oz.

Answer:

57 oz (the option with 57 oz, likely the last one in the list)
