Solution
This is a slightly difficult problem.
We know that Juan played in 4 games and struck out on an average of twice per
game. Thus the total number of times Juan struck out was
4 x 2 = 8 times.
Let us assume that he struck out 'Z' times in the first game.
Since he struck out a total of 8 times, we write the equation as
number of strike outs: Z + 0 + 0 +
0 = 8 times
game number: (1st) (2nd)
(3rd) (4th) (total)
Thus we find Z = 8.
Hence Juan struck out 8 times in the first game
