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

Which of these statements is correct? the system of linear equations 6x - 5y = 8 and 12x - 10y = 16 has no solution. the system of linear equations 7x + 2y = 6 and 14x + 4y = 16 has an infinite number of solutions. the system of linear equations 8x - 3y = 10 and 16x - 6y = 22 has no solution. the system of linear equations 9x + 6y = 14 and 18x + 12y = 26 has an infinite number of solutions.
