where d is the total amount he has saved so far.

![325=80+75m](https://img.qammunity.org/2020/formulas/mathematics/middle-school/ohshujrncgm31tz055mxguyx1a20nks71u.png)
![245=75m](https://img.qammunity.org/2020/formulas/mathematics/middle-school/aur3oswf4hr45tyl74efyp4i143i30c0as.png)
![(245)/(75)=m](https://img.qammunity.org/2020/formulas/mathematics/middle-school/bu6ups8reu3n35ichb5xqlh0jf8948o8jd.png)
![3.266=m](https://img.qammunity.org/2020/formulas/mathematics/middle-school/i4otdired7dtyxlkq28a5gl1fk0xt5sscq.png)
Thus,the first month in which Jordan will have saved enough money to buy the laptop is Month 4.
