13 cases

Explanation:

we know that

You have 1 case of soap bars

There are 150 bars in a case

You use 300 bars of soap per day ----> 2 cases per day

using proportion

Find how many cases do you need to order to have enough for 7 days

Let

x ----->the number of cases

2/1=x/7

x=2*7=14 cases

but remember that you have 1 case

so

you needed 14-1=13 cases
