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
