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

B4.3c + 1.9(c + 14) = 34.8

C4.3c + 1.9(12) = 34.8

D1.9c + 4.3(12 − c) = 34.8
