Answer:

  • Ribeye steak dinner ≈ $16.01
  • Grilled salmon dinner ≈ $19.91

Explanation:

  • <em>Number of ribeye steak dinners sold = x</em>
  • <em>Number of grilled salmon dinners sold = y</em>

Create two equations showing the amount sold and earned each day:

\left \{ {{20x+12y=559.11} \atop {29x+6y=583.72}} \right.

Solve the system of equations:

\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

Jar B has 20% more
LekaFEV [45]
8 1/3% of Jar B’s marbles need to be moved to jar A to make them equal. This is because:

If Jar A has 100 marbles and B has 120 marbles which is 20% more than Jar A then 10 marbles would have to be moved from Jar B to Jar A. To calculate the percentage it would be 10/120 which reduces to .0833 repeating or 8 1/3%.

Hope this helps :)
