Answer:
She made 17 three-point shots.
Explanation:
Let t represent the number of three-point shots she made.
Since, she made a total of 87 shots (two- or three-point shots), the number of two-point shots will be 87-t.
The points from three-point shots:
→ 3t (1)
The points from two-point shots:
→ 2(87-t) (2)
Since, her total point was 191, the sum of equation 1 and equation 2 must be equal to 191.
→ 3t + 2(87-t) = 191
→ 3t + 174 - 2t = 191
→ t = 17
