everyone at Luke's party has 2 balloons except Ashley, because one of her balloons popped. There are 17 balloons at the party. How many people are at the party?
18/2 = ?
To determine the number of people at the party, we can start by finding the total number of balloons initially present and then subtracting the popped balloon.
We are given that everyone at the party, except Ashley, has two balloons. Let's assume there are "x" number of people at the party (including Ashley), so the total number of balloons initially present should be 2x.
We are also given that there is a total of 17 balloons at the party, but one of Ashley's balloons popped. Therefore, the number of balloons initially present (2x) minus the popped balloon (1) should equal 17.
2x - 1 = 17
To solve for "x," we can add 1 to both sides of the equation:
2x - 1 + 1 = 17 + 1
2x = 18
Now, we can divide both sides of the equation by 2 to isolate "x":
2x/2 = 18/2
x = 9
So, there are 9 people at the party, including Ashley.
