Answer:

\$80.50

Step-by-step explanation:

Let

n ----> represent the number of tickets purchased

y --->   the total cost for a visit to the carnival in dollars

we know that

The linear equation in slope intercept form is equal to

y=m(n)+b

where

m is the slope or unit rate of the linear equation

b is the y-intercept or initial value

In this problem we have

The unit rate or slope is equal to

m=\$3.50\ per\ ticket

The y-intercept is equal to the cost for enter (value of y when the value of x is equal to zero)

b=\$10.50

substitute

y=3.50(n)+10.50

For n=20 tickets

substitute the value of n and solve for y

y=3.50(20)+10.50

y=\$80.50
