Explanation:
Let w represent the number of weeks and r represent the retirement account.
We have been given that Jerry Marcos is paid $11 per hour and works 40 hours per week. So money earned by Jerry per week will be equal to the number of hours Jerry worked per week times the amount earned per hour.
![\text{Jerry earns per week}=\text{Number of hours Jerry worked per week* Wages per hour}](https://img.qammunity.org/2020/formulas/mathematics/high-school/fewueelm7kt5qzezpniws5jz1xo74bu943.png)
![\text{Jerry earns per week}=40\text{ Hours}* (\$11)/(hour)](https://img.qammunity.org/2020/formulas/mathematics/high-school/blsmzw7xd6c96uwdvdtyykc7abwxshsu7r.png)
![\text{Jerry earns per week}=40*\$11](https://img.qammunity.org/2020/formulas/mathematics/high-school/yfavcr6cufb006aw9p6n08loah1zkb5xmn.png)
![\text{Jerry earns per week}=\$440](https://img.qammunity.org/2020/formulas/mathematics/high-school/ucnay1hjkp3o2de0g9q4uoyov5dsmq7pi2.png)
Since Jerry earns $440 per week, so amount earned by Jerry in w weeks will be 440w.
We have been given that Jerry puts 5% of the amount he makes per week into a retirement account (r), so amount in the retirement account after w weeks will be 5% of 440w.
We can represent this information in an equation as:
![r=(5)/(100)* 440w](https://img.qammunity.org/2020/formulas/mathematics/high-school/jxw4sjl2jd0sa3q967h9r9wr7by4qiqkue.png)
Upon simplifying our equation we will get,
![r=0.05* 440w](https://img.qammunity.org/2020/formulas/mathematics/high-school/e5id7jthxdl1jfc3g3swn3wsay4hidwo9b.png)
![r=22w](https://img.qammunity.org/2020/formulas/mathematics/high-school/fqq363sch5vr3mtrlke3pqmu6ruoxkfxs8.png)
Therefore, the equation
can be used to find the amount put by Jerry in his retirement account after a certain number of weeks.
