16x - 3 + 5x + 2 = 72
21x - 1 = 72
21x = 72+1
21x = 73
x = 73/21
x ≈ 3.48

Distance from Diego's house to the restaurant:
16x - 3 = 16 * 3.48 - 3 ≈ 52.6 miles

Distance from Anya's house to the restaurant: 
5x + 2 = 5 * 3.48 + 2 ≈ 19.4 miles

52.6 ≠ 19.4  ⇒ <span>Diego was wrong.</span>

Travka [436]
Probability is 1/4, so all you have to do is multiply 80 by 1/4, which equals 20. 

So, she will likely hit 20 foul balls.
