The Kickers scored twice as many as 2 goals in the second period, so 2*2 = <<2*2=4>>4 goals
The Spiders scored half as many as The Kickers' 2 goals from the 1st period so .5*2 = <<2*.5=1>>1 goal in the first period
The Spiders scored twice as many as The Kickers' 4 goals from the second period, so 2*4 = <<2*4=8>>8 goals in the second period
Together, they scored 2+4+1+8 = <<2+4+1+8=15>>15 goals total
