1. the county fair charges $1.25 per ticket for the rides. jermaine bought 20 tickets for the rides and spent a total of $35.00 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.

2. a line goes through the points (-4,3) and (4,9).

(a) what is the slope of the line? show your work

(b) write the equation of the line in point-slope form. show your work

(c) write the equation of the line in slope-intercept form. show your work.

3. jacob and sarah are saving money to go on a trip. they need at least $2000 in order to go. jacob mows lawns and sarah walks dogs to raise money. jacob charges $20 each time he mows a lawn and sarah charges $10 each time she walks a dog.

write an inequality to model the problem, with x representing the number of lawns mowed and y representing the number of dogs walked.
