Aaron is going to a carnival that has games and rides. each game cost $2.75 and each ride cost $4.75. aaron spent $20.50 altogether at the carnival and the number of games he played is twice the number of rides he went on. determine the number of games aaron played and the number of rides aaron went on.

Aaron played 4 games and went on 2 rides at the carnival.

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Cost of each game = US$ 2.75

Cost of each ride = US$ 4.75

Total spent by Aaron at the carnival = US$ 20.50

Number of rides = x

Number of games = 2x (the number of games he played is twice the number of rides he went on)

2. Determine the number of games Aaron played and the number of rides Aaron went on.

For determine the number of games and the number of rides, we will use the following equation:

2.75 (2x) + 4.75x = 20.50

5.5x + 4.75x = 20.50

10.25x = 20.50

x = 20.50/10.25

x = 2 ⇒ 2x = 4

Aaron played 4 games and went on 2 rides at the carnival.

step-by-step explanation:

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
