Admission to school carnival costs $10, and each activity costs $2. What type of function should be used to model the total amount spent by each person that attends the carnival?
a. exponential
b. linear
c. neither
d. cannot be determined

b.linear

Step-by-step explanation:

we know that

The linear equation in slope intercept form is given by

where

y is the total amount spent

x is the number of activities

m is the slope or unit rate

b is the y-intercept or initial value

In this problem we have that

The slope or unit rate of the situation is equal to

The y-intercept or initial value is equal to

substitute the given value

The equation that represent this problem is

therefore

The situation can be modeled with a linear function
