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?

**
First, we will need to find the number of cases needed per day: We know that one case includes 150 bars and that the daily consumption is 300 bars. To know the number of cases needed daily, we will use cross multiplication as follows: 1 case .............> 150 bars ?? cases .........> 300 bars number of cases needed daily = 150 300 ∗ 1 ​ number of cases needed daily = 2 cases
Then, we will get the number of cases needed weekly (7 days): We know that 2 cases are needed daily. To know the number of cases needed weekly (7 days), we will simply use cross multiplication as follows: 1 day .............> 2 cases 7 days ...........> ?? cases number of cases needed weekly = 1 7 ∗ 2 ​ number of cases needed weekly = 14 cases
Hope this helps :)

The student needs to order 14 cases of soap bars to have enough for 7 days. This is calculated by first determining the total number of bars needed (2100) and then dividing that by the number of bars in a case (150). Therefore, 14 cases are required to meet the daily soap usage.
