Answer:
The linear function is: p(x) = 3x+65The linear function is: p(x) = 3x+65
Step-by-step explanation:
Let x be the number of t-shirts and y be the total pay
As we can clearly see in the table that there is a linear relationship between x and y
A linear function is given as:

Here m is the gradient of the function then

Taking any two pairs of x and y
(1,68) and (2,71)

Putting in equation

Putting a pair (1,68) in the equation to find the value of b

Putting the value of b

Let p(x) be the linear function
Hence,
The linear function is: p(x) = 3x+65
Answer:
Step-by-step explanation:
8x=180-8
8x=172
8x/8=172/8
x=21.5
Your answer would be A as the annual rate increases, so does the monthly.
