Cost of Lunch Orders Calculation

What are the costs of the Turkey Sandwich, Panini, and Salad?

Given the total cost for each day's lunch orders, how can we determine the individual costs of each item?

Answer:

The cost of a Turkey Sandwich is $7.99, the cost of a Panini is $8.99, and the cost of a Salad is $5.99.

Reflecting on the lunch orders placed throughout the week and the total costs incurred, it is clear that we need to calculate the cost of each item ordered. By setting up a system of equations based on the quantities ordered and total costs, we can solve for the individual costs of the Turkey Sandwich, Panini, and Salad.

Let's assume the cost of a Turkey Sandwich is 'x', the cost of a Panini is 'y', and the cost of a Salad is 'z'. We can then establish the following equations:

6x + 9y + 9z = $184.14
2x + 6y + 2z = $72.64
3x + 9y + 9z = $157.50

By solving this system of equations, we can find the values of 'x', 'y', and 'z', which will represent the costs of each item. The results show that a Turkey Sandwich costs $7.99, a Panini costs $8.99, and a Salad costs $5.99.
