Problem
The players on a basketball team made some three-point shots, some two-point shots, and some one-point free throws. They scored as many points with two-point shots as with three-point shots. Their number of successful free throws was one more than their number of successful two-point shots. The team's total score was points. How many free throws did they make?
Solution 1
For the points made from two-point shots and from three-point shots to be equal, the numbers of made shots are in a ratio. Therefore, assume they made and two- and three- point shots, respectively, and thus free throws. The total number of points is
Set that equal to , we get , and therefore the number of free throws they made
Solution 2
Let be the number of free throws. Then the number of points scored by two-pointers is and the same goes for three-pointers because they scored the same number of points with twos and threes. Thus, our equation is , giving us for an answer.
