Question

Kiran is spending $12 on games and rides at another carnival, where a game

costs $0.25 and a ride costs $1.
1. Write an equation to represent the relationship between the dollar
amount Kiran is spending and the number of games, x, and the number of
rides, y, he could do.

Answer 1

0.25x + y = 12

Explanation:

Given

Kiran is spending $12 on games

it means that he can spend total of $12 on rides and games

number of games is represented by x

cost of 1 game = $0.25

cost of x games = $0.25*x = $0.25x

number of rides is represented by y

cost of 1 rides = $1

cost of x rides = $1*y = $y

Total cost for x games and y rides =cost of x games + cost of y rides

Total cost for x games and y rides = $0.25x + $y

given that Kiran is spending $12 on games

Total cost for x games and y rides will be $12

thus,

$12 = $0.25x + $y

removing dollar sign for equation formation

0.25x + y = 12

given above is the equation to represent the relationship between the dollar

amount Kiran is spending and the number of games, x, and the number of

rides, y.
