so, Pat needs to save the minimum amount of $170.83 per month
Step-by-step explanation
Step 1
Let
total = 14500
grandparents=3600
so, the total equals what the grandparents gave him plus what he can save
![14500=6300+x](https://img.qammunity.org/2023/formulas/mathematics/college/99isg294ho2e0go5a4g97ebtiz9zgcxlko.png)
but, he will save the same amount of money every month
4 years= 48 months
let y represents the amount he saves per month ,so
x=48*y
now, replace
![14500=6300+48y\rightarrow equation](https://img.qammunity.org/2023/formulas/mathematics/college/uxf4exku7znb90flkwmhxvc250om8wsic1.png)
Step 2
solve the equation
![\begin{gathered} 14500=6300+48y\rightarrow equation \\ \text{subtract 6300in both sides} \\ 14500-6300=6300+48y-6300 \\ 8200=48y \\ \text{divide both sides by 48} \\ (8200)/(48)=(48y)/(48) \\ 170.83=y \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/bkyag6vgji7zwg2wxkex7v2wridiydzweb.png)
so, Pat needs to save the minimum amount of 170.83 per month
I hope this helps you
