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?

A. 7c + 5g + 6

B. 7c + 5g + 12

C. 14c + 5g + 6

D. 14c + 5g + 12

Answer 1

Let's first have a look at the admission fee, which is $6,- per person.

This makes a total of $12,-

(Since 6 x 2 = 12).

Next up, the ride at the carnival. This costs c dollars.

This makes a total of 14c

(Since they have made a total of 14 rides (7 each), and we multiply it by 'c')

Finally the game boots, which costs g dollars a game.

Denise and Stacey played a total of 5 games, hence the total cost of the boots will be 5g.

The total cost will therefore be: 14c + 5g + 12

This makes the fourth answer (in your question) the correct answer.

Answer 2

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.
