<span><u><em>Answer:</em></u>
14 cases
<u><em>Explanation:</em></u>
<u>First, we will need to find the number of cases needed per day:</u>
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 = </span>
<span>
number of cases needed daily = 2 cases
<u>Then, we will get the number of cases needed weekly (7 days):</u>
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 = </span>
<span>
number of cases needed weekly = 14 cases
Hope this helps :)</span>
