80 = 5 x 4 x 4
they have 4 flavors of icecream
you get this by multiplying all the variables and how many different possibilities each variable can be
so,
5 different syrups (5)
4 different candy toppings (4)
from that you know 5 x 4 x ? = 80
so 5 x 4 = 20, and 20 x 4 = 80
so 4 different flavors of ice cream (4)
Aftershocks occur after the most major part of an earth quake happens. Earthquakes occur at fault lines near the tectonic border. They occur because of the sudden movement for staying rigid while they were edging closer and closer. So the sudden movement releases a large amount of tension buried deep below the earth creating or resulting in an earthquake.
