Question

Denise and Stacey went to a carnival. The admission fee was $6 per person. Each ride at the carnival costs c dollars. The game booths charged g dollars for each game. Both Denise and Stacey went on 7 rides each. Stacey played 3 games, while Denise played 2 games. Which expression represents the total amount of money that Denise and Stacey spent at the carnival?

Answer 1

The correct answer is D. 14c + 5g + 12.

The entry fee is $6 each. 6 + 6 = 12

Each girl goes on 7 rides which cost c dollars. 7c + 7c = 14c

The number of games both girls play totals 5. And each game costs g dollars. 2g + 3g = 5g.

Add all the costs up and you get 14c + 5g + 12 as their total cost for going to a carnival.

Answer 2

Denise's equation: D = 6 + 7c + 2g
Stacey's equation: S = 6 + 7c + 3g.

Because they are asking for the total, you can combine like terms and will get:

12 + 14c + 5g. If you have to put it in standard form, you can do 14c + 5g + 12 or 5g + 14c + 12.
