Gavin is a Highschool bascketball player. In a particular game, he made some free throws and some three point shots. Gavin made a total of 13 shots altogether and scored a total of 25 points. Determine the number of free throws Gavin made and the number of three point shots he made.

1 answer

Let \( x \) be the number of free throws Gavin made, and \( y \) be the number of three-point shots he made. We can set up the following system of equations based on the problem statement:

  1. The total number of shots made: \[ x + y = 13 \]

  2. The total points scored (free throws are worth 1 point, and three-point shots are worth 3 points): \[ x + 3y = 25 \]

Now we can solve this system of equations. We can start by solving the first equation for \( x \): \[ x = 13 - y \]

Next, we substitute \( x \) in the second equation: \[ (13 - y) + 3y = 25 \]

Simplifying this: \[ 13 - y + 3y = 25 \] \[ 13 + 2y = 25 \]

Now, isolate \( y \): \[ 2y = 25 - 13 \] \[ 2y = 12 \] \[ y = 6 \]

Now that we have \( y = 6 \), we can find \( x \) using the first equation: \[ x + 6 = 13 \] \[ x = 13 - 6 \] \[ x = 7 \]

Thus, the number of free throws Gavin made is \( 7 \) and the number of three-point shots he made is \( 6 \).

To summarize, Gavin made:

  • Free throws: \( 7 \)
  • Three-point shots: \( 6 \)

We can verify our solution:

  • The total number of shots is \( 7 + 6 = 13 \).
  • The total points scored is \( 7 \cdot 1 + 6 \cdot 3 = 7 + 18 = 25 \).

Both conditions are satisfied, confirming that our solution is correct.
