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?
If you need enough for 7 days, and you use 300 bars a day (which is two cases a day) then you would multiply two by seven. And get fourteen. You would need 14 cases for 7 days worth of soap.
