It can help because 9×4 =36, and 9×8=72. if you divide 72 by 2 you get 36 which is the answer to 9 ×4. basically because nine is the same in both problems you are multiplying by 4 (and you know 4 is half of 8) you can assume that multiplying the sum of 4 and 9 that you will get the sum of 8 and 9.

Answer:
1.15
Step-by-step explanation:
Multiply each shot by its point value. Then add. Divide this sum by the total number of shots taken.
288*2 + 79*3 + 340*0 = 813
----------------------------------------
288 + 79 + 340 = 707
813 / 707 = 14.992
The weighted average is approximately 1.15 points per shot.
