Karin at the carnival

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, , and the number of rides, , he could do.

1. Which graph represents the relationship between the quantities in this situation? Explain how you know.

A

A

B

C

Answer 1

25x + 100y = 1200 in cents

or .25 x + y = 12 in dollars

x= games y= rides

IF y=0 x = 48

if x=0 y = 12

the graph will connect the x axis and y axis at the points where x= 48 and y= 12, Only graph C seems to have a line that may end at x=48
