1. the county fair charges $1.25 per ticket for the rides. jermaine bought 25 tickets for the rides and spent a total of $43.75 at the fair. jermaine spent his money only on ride tickets and fair admission. the price of the fair admission is the same for everyone. use y to represent the total cost and x to represent the number of ride tickets. (a) define your variables. (b) write a linear equation that can be used to determine the cost for anyone who only pays for ride tickets and fair admission. (c) explain your answer to part 1b.

If this were to be graphed, the independent variable would be the price of the ticket for the rides. The dependent variable would be the total cost.

The fair admission is not a variable because it is a constant price for every single person who goes into the fair.

The problem asks to use y to represent the total cost and x to represent the number of ride tickets. In order to fully write out the equation, we have to figure out what the fair admission costs.

43.75 = 1.25(25) + b

*b represents the fair admission

Multiply 1.25 by 25

43.75 = 31.25 + b

Subtract 31.25 to find what b costs.

12.50 = b

The fair admission costs $12.50.

Solution: y = 1.25x + 12.50

Ais the correct answer
