Question

Jada has $20 to spend on games and rides at a carnival. Games cost $1 each and rides cost $2 each.

Which equation represents the relationship between the number of games, x and the number of rides, y, that Jada could do if she spends all her money?​

Answer 1

x + 2y = 20

Explanation:

number of games = x

cost of 1 game = $1

cost of x games = $1*x = $x

number of rides = y

cost of 1 rides = $2

cost of y rides = $2*y = $2y

Total cost for x games and y rides = $x + $2y

given that he can spend all which he has

and he has $20

Then

Total cost for x games and y rides would be equal to total money had

thus

$x + $2y = $20

$ gets cancelled from both sides

thus

relationship between x and y will be

x + 2y = 20 Answer
