Answer:
24 points
2 shots
Explanation:
Ivan :
Starting point = 20
Points per success = 2
Brother :
Starting point = 16
Points per success = 4
Let number of successful shots = x
20 + 2x = 16 + 4x
2x - 4x = 16 - 20
-2x = - 4
x = 2
Number of additional shots made = x = 2
Number of points they both have :
20 + 2x = 20 + 2(2) = 20 + 4 = 24 points
16 + 4x = 16 + 4(2) = 16 + 8 = 24 points
