An international food festival charges for admission and for each sample of food. admission and 6 samples cost $8.25. admission and 8 samples cost $10.25. write a linear function rule to model the cost y for any number of samples x

y = x + 2.25

Step-by-step explanation:

First information: admission and 6 samples cost $8.25:

8.25 = 6a + b

Second information: admission and 8 samples cost $10.25:

10.25 = 8a + b

{6a + b = 8.25

{8a + b = 10.25

{- 6a - b = - 8.25

{8a + b = 10.25

2a = 2

a = 1

6a + b = 8.25

6.1 + b = 8.25

b = 8.25 - 6

b = 2.25

The linear function rule is:

y = x + 2.25
