In the first half of last year, a team won 60 percent of the games it played. In the second half of last yeas, the team played 20 games, winning 3 of them. If the team won 50 percent of the games it played last year, what was the total number of games the team played last year?


60/ 100 * x + 3 = 50/100 (x + 20)
0.6x + 3 = 0.5x + 10
0.1x = 7
x = 70

So the team played 70 games in the first "half" and "20" games in the second "half'
70 + 20 = 90

In Example 2, you can apply a property from geometry that says that when two chords intersect inside a circle, the segments formed have lengths such that the product of the segment lengths is the same for each chord. 2. Apply basic properties of numbers. In Example 4, you can use the definition of a prime number so that you do not include 1, but do include 2. 3. Eliminate as many answers as possible so that you can select from a smaller set of answer choices. In Example 3, you can eliminate some of the answers by noting that since each can of mixed nuts is at least 30% peanuts, the mixture of the two cans will be least 30% peanuts. Thus, before doing any computation, you could eliminate answers A, B, and C. Therefore, if you need to guess, you only have two answer choices left and have increased your odds of guessing correctly. 4. Substitute answers into the given question to see which one produces the ...
