Question

A shoe store offers a frequent-buyers card. Each transaction is worth 10 points, and customers

automatically earn 22 points when they sign up.
Enter the function rule for the transaction function, where p represents the number of transactions.
The function rule is N (p)=__
In graphing the function,___
would be the slope and___
would be the y-intercept.

Answer 1

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.

Explanation:

Let p represents the number of transactions.

Each transaction is worth 10 points, then p transactions are worth 10p points.

Customers automatically earn 22 points when they sign up.

The total amount of points is

N(p) = 22 + 10p

In graphing the function, N(p) = 22 + 10p

would be the slope and 10;

and 22 would be the y-intercept.
