You have 1 case of soap bars and there are 150 bars in a case. you use 300 bars of soap per day. how many cases do you need to order to have enough for 7 days? *

Let x= number of cases
150x=300
300/150=x
x=2
You will need 2 cases of soap every day.
To figure out how many cases you would need in a week:
2*7=14
You would need 14 soap cases in a week. 

Hope this helps!
