Question

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?

Answer 1

1 case = 150 bars
use 300 bars/day=300/150=2 case/day
7 days will use 7day*2case/day=14case

Answer 2

1 case = 150 soap bars.
You need 300 bars of bars of soap.
And need enough soap to last you 7 days.

300 / 150 = 2. Two cases a day. Now multiply 2 * 7. Which gives you 14.

So you'll need 14 cases of soap bars.
