Answer:

The total cost [tex]y[/tex] in dollars of going to the baseball game for [tex]x[/tex] people of a family can be given as:

[tex]y=21x+5[/tex]

Step-by-step explanation:

Given:

At a baseball game:

Cost of car parking = $5

Cost per ticket = $21

To write an equation in the form of [tex]y=mx+b[/tex] representing the total cost of going to the baseball game.

Solution:

The total number of people in the family is = [tex]x[/tex]

Using unitary method to find the cost of tickets for [tex]x[/tex] persons.

If 1 ticket costs = $21

Then, [tex]x[/tex] tickets will cost in dollars = [tex]21x[/tex]

Fixed rate for car parking = $5

Thus, the total cost [tex]y[/tex] in dollars of going to the baseball game for [tex]x[/tex] people of a family can be given as:

[tex]y=21x+5[/tex]
