Cara is grocery shopping and needs chicken and steak for the barbeque she is having on Saturday. Chicken is $2.99 per pound and steak is $5.79 per pound. She knows she wants to spend exactly $50 on meat. If c represents pounds of chicken and s represents pounds of steak, which equation represents this situation?
2.99s + 5.79c = 50
8.78m = 50
c + s = 50
2.99c + 5.79s = 50
