Jenna buys 12 lb of meat. Some of the meat is chicken and costs $1.90/lb. The rest is beef, which costs $4.30/lb. She spends a total of $34.80.

Which equation models this situation?

Let c represent the number of pounds of chicken she buys.

A.

(1.9 + 4.3)(12 – c) = 34.8

B.

4.3c + 1.9(c + 14) = 34.8

C.

4.3c + 1.9(12) = 34.8

D.

1.9c + 4.3(12 − c) = 34.8
