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

Best ResponseYou've already chosen the best response.0c is the pounds of chicken she buys. And she pays $1.90 for each pound. So the total amount she pays for chicken is the 1.90 * c

Best ResponseYou've already chosen the best response.1well the total of chicken and beef is 12 pounds let pounds of chicken=c and let pounds of beef=b so c+b=12 ok?

Best ResponseYou've already chosen the best response.1and you know it cost 1.9 per pound of chicken, which you can write as 1.9c and 4.3 per pound of beef, which is the same as 4.3b and you know the total cost is 34.80. can you try to make an equation using these three information?

Best ResponseYou've already chosen the best response.1not exactly given that info. you're equation would be 1.9c + 4.3b=34.80 but remember our earlier equation. c+b=12 we want to isolate c so we have c=12b now substitute this into the other equation
