B. 878
C. 896
D. 915
E. 932

Answer :

To solve the problem of converting 2 pounds of ground meat into grams, we can follow these steps:

1. Understand the conversion between pounds and ounces: There are 16 ounces in a pound. So for 2 pounds, we need to calculate the total ounces:
[tex]\[
2 \text{ pounds} \times 16 \text{ ounces per pound} = 32 \text{ ounces}
\][/tex]

2. Use the given conversion between ounces and grams: We know that 5 ounces is equal to 140 grams. To find out how many grams are in 1 ounce, divide 140 grams by 5 ounces:
[tex]\[
\frac{140 \text{ grams}}{5 \text{ ounces}} = 28 \text{ grams per ounce}
\][/tex]

3. Convert the total ounces of meat to grams: Now, multiply the total ounces (32 ounces) by the number of grams per ounce (28 grams):
[tex]\[
32 \text{ ounces} \times 28 \text{ grams per ounce} = 896 \text{ grams}
\][/tex]

Therefore, 2 pounds of ground meat is equal to 896 grams.
