Commission of sales = 10%
Total sales of last week = $1,000.
To find:
The the total money did joe make.
Solution:

Commission of sales = 10%
Total sales of last week = $1,000
![\text{Commission}=10\%\text{ of }1000](https://img.qammunity.org/2022/formulas/mathematics/high-school/m7ujvhnqx9br5t9dmjsexd2wadk0w3p9qi.png)
![\text{Commission}=(10)/(100)\text{ of }1000](https://img.qammunity.org/2022/formulas/mathematics/high-school/wsmezbg3fav29qv2j560a012xe3x9xogbx.png)
![\text{Commission}=100](https://img.qammunity.org/2022/formulas/mathematics/high-school/ymajfmxhfdo8utce39qdkx6h7rw4p3x7k6.png)
Now,
Total weekly income = Weekly fixed salary + Commission
![=350+100](https://img.qammunity.org/2022/formulas/mathematics/high-school/ts3y15ccmxl4lzzt3jruol6dvi064dvf8p.png)
![=450](https://img.qammunity.org/2022/formulas/mathematics/high-school/86v6ifwvbr9a5x8d2uyyeg6us8sxcb8cfm.png)
Therefore, the total income of Joe for last week is $450.
