1. the cajun heartland state fair charges $1.25 per ticket for the rides. johnny bought 25 tickets for the rides and spent a total of $43.75 at the fair. johnny 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

Let number of ride tickets = x tickets and

Total cost of fair admission and ride = $y.

Given cost of each ticket = $1.25 and

Number of tickets = 25 tickets.

Total Cost of 25 ticket  = Number of tickets * cost of each ticket = 25 * 1.25 = $31.25.

Total money spent = $43.75.

Total money spent  =  Fair admission  + Total Cost of 25 ticket

43.75 = Fair addmission + 31.35.

Subtracting 31.25 from both sides, we get

43.75-31.35 = y - 31.35 - 31.35.

12.50 = Fair addmission charge

Therefore, Fair addmission charge = $12.50.

We know slope, intercept form

y = mx+b.

Where, is m the slope (cost of each ticket) and b is the y-intercept( Fair addmission charge)

Plugging values in slope-intercept form, we get

y = 1.25 x+ 12.50.

a) We took x for number of tickets for the rides, and y for total cost of ride tickets and fair admission.

b) We got equation y = 1.25 x+ 12.50.

c) For the equation y = 1.25 x+ 12.50, fix charge for fair admission is $12.50 and cost of each ride ticket is $1.25. Total cost (y) of ride tickets and fair admission will be 1.25 times x number of tickets + $12.50 fair admission charges.

first, we define the variables:

x: number of years after 1950

f (x): amount of vinyl sold.

then, with the variables defined, we have:

68594 vinyl records were sold in 1958 > f (8) = 68594

91299 vinyl records were sold in 1961 > f (11) = 91299

38720 vinyl records were sold in 1952 > f (2) = 38720

161743 vinyl records were sold in 1967 > f (17) = 161743
