ANSWER
$176.10
EXPLANATION
To find the profit we have to subtract what the store paid for the 3 cases ($165.90) from the total charge the store makes for 3 cases.
If each jar costs $4.75 and 1 case contains 24 jars, then the charge for one case is: $4.75 x 24. Now, if one case costs that, then 3 cases cost 3 times that:
[tex]4.75\times24\times3=342[/tex]The profit is:
[tex]342-165.90=176.10[/tex]
