A waitress sold 20 ribeye steak dinners and 12 grilled salmon dinners, totaling $559.11 on a particular day. Another day she sold 29 ribeye steak dinners and 6 grilled salmon dinners, totaling $583.72 How much did each type of dinner cost?
Answer:
Ribeye steak dinner ≈ $16.01Grilled salmon dinner ≈ $19.91Explanation:
Number of ribeye steak dinners sold = xNumber of grilled salmon dinners sold = yCreate two equations showing the amount sold and earned each day:
[tex]\left \{ {{20x+12y=559.11} \atop {29x+6y=583.72}} \right.[/tex]
Solve the system of equations:
[tex]\left \{ {{20x+12y=559.11} \atop {29x+6y=583.72}} \right.\\\\=\left \{ {{20x+12y=559.11} \atop {29(2)x+6(2)y=583.72(2)}} \right.\\\\=\left \{ {{20x+12y=559.11} \atop {58x+12y=1167.44}} \right.\\\\(20-58)x+(12-12)y=559.11-1167.44\\\\-38x=-608.33\\\\x=\frac{-608.33}{-38} =16.01\\\\20x+12y=559.11\\20(16.01)+12y=559.11\\12y=559.11-20(16.01)\\12y=238.91\\y=19.91[/tex]
If we wanted to explore the idea that mother's smoking might explain the variation in birth weight, what visualization might be helpful to us?

Hope this helped.
