Step-by-step explanation
Let the sales be represented by x
Since the person earns 6.5% of the sales, this becomes;
![(6.5)/(100)* x=0.065x](https://img.qammunity.org/2023/formulas/mathematics/college/4ikm7ow3hdthjagszqm8yh6xirkpei8fjj.png)
Recall that at least implies greater than or equal to in inequality. Therefore, the equation becomes;
![0.065x+1500\ge3350](https://img.qammunity.org/2023/formulas/mathematics/college/y7e53kxz45da6wse3qmm42f16mqwt0a2rr.png)
We will then solve for x
![\begin{gathered} 0.065x\ge3350-1500 \\ 0.065x\ge1850 \\ x\ge(1850)/(0.065) \\ x\ge28461.5385 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/j2xz3yzyz5swv6n7u732brwwxr2nt3jzvb.png)
Answer: $28461.5385
