Question

Jada has $20 to spend on games and rides at a carnival. Games cost $1 each and rides are $2 each. Let x represent the number of games and y

represent the number of rides.

If Jada plays 5 games, how many rides can she go on?

If jada plays 5 games, she could go on _________ rides.

Answer 1

Jada can go on 7 rides.
Since games are $1 and she played 5, she spent $5 on those.
Now she has $15 and rides are $2 so she can go on 7 of them and have a remaining $1

Answer 2

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 Answ
