I'm not really sure what this means, but i'll do what i think is right!
Answer:
Steve: $138
Jenna: $72
Explanation:
If you're doing it so they each get what they sold, you would have to first add the total number of chocolate bars, giving you 35. To see how much each bar costs, you just have to divide $210 รท 35, giving you $6 per chocolate bar.
To give each what they gained, you multiply $6 by whichever amount you chose, 23 or 12, which will give you that person's amount. Steve will get $138 and Jenna will get $72.
hope this helps!
