Answer:

Total Cost : y = 2.75 + m (1) , where m = cost of each item

Explanation:

The cost of admission and 3 samples = $5.75

The cost of admission and 6 samples = $8.75.

Cost is represented by y ,

The number of Samples = x

Let the admission charge is each case = $ a.

Total Cost y = a + (Number of items tasted x Cost of each item)

So, according to the question:

First Case:

a + 3x = $ 5.75

Second Case:

a + 6x = $ 8.75

Solving the above system of equations, we get a = $ 2.75

And , if a = $2.75 then x = 1

Hence, the Total Cost y = 2.75 + m (1) , here m = cost of each item
