Basketball Scoring Problem: Solve for (a+4) Close-Range Shots with 56 Total Points

Question

A basketball player scores 3 points for each long-range shot and 2 points for each close-range shot.

He scores a total of 8 long-range shots and a+4 a+4 close-range shots.

How many shots does he score in total if he gets 56 points?

Step-by-Step Solution

To solve this problem, we'll follow these steps:

  • Step 1: Calculate the total points from long-range shots.
  • Step 2: Formulate an equation for total points scored.
  • Step 3: Solve for unknown a a using algebra.
  • Step 4: Determine the total number of shots.

Now, let's work through each step:

Step 1: Compute points from long-range shots: The player makes 8 long-range shots, each worth 3 points. Thus, the total points from long-range shots are: 3×8=24 3 \times 8 = 24

Step 2: Set up the total points equation. Let the points from close-range shots be denoted by 2×(a+4) 2 \times (a + 4) . The total points scored is 56, so the equation becomes: 24+2×(a+4)=56 24 + 2 \times (a + 4) = 56

Step 3: Solve for a a . Expanding the equation, we get: 24+2a+8=56 24 + 2a + 8 = 56 Simplify the equation: 2a+32=56 2a + 32 = 56 Subtract 32 from both sides: 2a=24 2a = 24 Divide by 2 to solve for a a : a=12 a = 12

Step 4: Calculate the total number of shots. Plugging a=12 a = 12 back into the expression for close-range shots, we get a+4=16 a+4 = 16 . Therefore, the total shots are 8+16=24 8 + 16 = 24 .

Therefore, the solution to the problem is 24.
