Order of the brother:
• Bacon and eggs --> $3.99
,
• Milk --> $0.95
,
• Pancakes --> $2.55
We add the prices to find how much he spend:
![3.99+0.95+2.55=7.49](https://img.qammunity.org/2023/formulas/mathematics/college/j0ieeswlzrxesccag0zdi3us69p4k7uqtp.png)
The brother spend $7.49
Your order:
• Chicken -->$4.74
,
• Shrimp --> $4.10
,
• Lemonade --> $0.77
We add the prices to find how much you spend:
![4.74+4.10+0.77=9.61](https://img.qammunity.org/2023/formulas/mathematics/college/sh5ugb2jh0u1l43zn0fgbpt3k6rmor0dq3.png)
You spend $9.61
To find the difference in price between the two orders we substract the price that the brother pay, from what you pay:
![9.61-7.49=2.12](https://img.qammunity.org/2023/formulas/mathematics/college/y2kv3dxb790jng17d7w9ghdog0qmipfkz5.png)
The difference is $2.12
Finally, if they split the bill equally, we need to add the two costs and divide them by 2 to find how much each person will pay:
![7.49+9.61=17.1](https://img.qammunity.org/2023/formulas/mathematics/college/1kgjq0wk2jqq3voflv336bqwo4iucfcalf.png)
Dividing by 2:
![(17.1)/(2)=8.55](https://img.qammunity.org/2023/formulas/mathematics/college/fj48lg4a5g63twdrkno0a7oaji46b3yd2x.png)
If they split the bill, each will pay $8.55
