18 × 3 = 54
Fran made 54 three point shots for the season.
12 × 1 = 12
Fran made 12 one point shots for the season.
Add the three point shots and one point shots together:
54 + 12 = 66
Now, subtract 66 (Number of three point shots and one point shots) from 102 (Total amount of shots)
102 - 66 = 36
36 ÷ 2 = 18
So, Fran made 18 two point shots for the season (Which resulted in 36 points)
And there's your answer!
