We are also told that another day she sold 28 ribeye steak dinners and 13 grilled salmon dinners, totaling $584.01. We can represent this information in an equation as:
Now, we will use substitution method to solve our system of linear equations. From equation (1), we will get:
Upon substituting this value in equation (2), we will get:
Therefore, cost of each grilled salmon dinner is $14.13.
(A) To find the cost of each ribeye dinner, we will substitute in equation
.
