Answer:
$11,250
Explanation:
Yvonne earns a fixed amount of $1,850 per month and want to earn $2,300. The difference is
![\$2,300-\$1,850=\$450.](https://img.qammunity.org/2020/formulas/mathematics/high-school/bi0iiadc6709za0d7v5rv83w613prmz53b.png)
This difference is her commission. If she earns the commission of 4% on the amount of goods that she sells, then
$x - 100%
$450 - 4%
Make a proportion:
![(x)/(450)=(100)/(4)\Rightarrow 4x=45,000\\ \\x=(45,000)/(4)\\ \\x=\$11,250](https://img.qammunity.org/2020/formulas/mathematics/high-school/2fxq3hrouq34uci0epcyilvanlqz853jgr.png)
Yvonne must sell $11,250
