Here are two stories:
Story 1: A family buys 6 tickets to a show. They also each spend $3 on a snack. They spend $24 on the show.
Story 2: Diego has 24 ounces of juice. He pours equal amounts for each of his 3 friends, and then adds 6 more
ounces for each.
Here are two equations:
3(x + 6) = 24
6(x+3) = 24
Which equation represents Story 1?
Answers
The second equation i.e. 6(x + 3) = 24 represents the scenario of Story 1.
Story 1 Scenario :
- Story 1 has 6 family members.
- Each of the members has expenses for food and movie.
- The expense of food for each of the member is given as 3 dollars
- Let us assume the expense of a movie per member be "x" dollars
So, forming the equation :
Total cost = number of members * total cost of each member
= number of members * ( cost of food + cost of movie ) for each
Replacing the equation with numbers :
Story 2 Scenario :
- Story 2 has 3 friends or members
- Each of the friends is poured initially an equal amount of liquid and then 6 more ounces
- The additional juice poured into each in the last is 6 ounces.
- Let us assume the initial juice poured be "x" ounces
So, forming the equation :
Total juice = number of friends * total juice distributed to each friend
= number of friends * ( equal amount + additional ) for each
Replacing the equation with numbers :
Hence, the equation for Story 1 is the second option i.e. 6(x+3) = 24.

The equation that represents Story 1 is 3(x+6) = 24.
To understand why, let's break down the story. A family buys 6 tickets to a show, and each person spends $3 on a snack. We can represent the cost of the tickets as 6x, where x is the cost of one ticket. We can also represent the cost of the snacks as 3(6), since there are 6 people each spending $3.
The total cost of the tickets and snacks is 6x + 18. However, we also know that they spent a total of $24 on the show. So, we can set up the equation:
6x + 18 = 24
To solve for x, we can subtract 18 from both sides:
6x = 6
And then divide both sides by 6:
x = 1
So the cost of one ticket is $1.
Now we can plug in the value of x into the expression for the cost of the snacks:
3(6) = 18
So the total cost of the tickets and snacks is:
6(1) + 18 = 24
Therefore, the equation that represents Story 1 is 3(x+6) = 24.
