Samuel bought an 8-ounce bag of lettuce and two 1-pound bags of carrots.

Which is the total weight of the lettuce and carrots in ounces?

A.
10 ounces

B.
12 ounces

C.
40 ounces

D.
72 ounces

The lettuce weighs 8 ounces and the carrots weigh 2 pounds each, which is equivalent to 32 ounces each. So, the total weight is:

8 ounces (lettuce) + 32 ounces (carrots) + 32 ounces (carrots) = 72 ounces

Therefore, the answer is D. 72 ounces.

To find the total weight of the lettuce and carrots in ounces, we need to calculate the weight of each item and then add them together.

The bag of lettuce weighs 8 ounces.

Each bag of carrots weighs 1 pound, which is equivalent to 16 ounces. Since Samuel bought two bags of carrots, the total weight of the carrots is:

2 bags * 16 ounces per bag = 32 ounces

Now, we can add the weight of the lettuce and carrots together:

8 ounces (lettuce) + 32 ounces (carrots) = 40 ounces

Therefore, the correct answer is C. 40 ounces.
