Answer: ![x\geq 88](https://tex.z-dn.net/?f=x%5Cgeq%2088)
This means that he has to save at least $88 or more to have enough money.
Step-by-step explanation:

![37+x\geq 125](https://tex.z-dn.net/?f=37%2Bx%5Cgeq%20125)

![x\geq125-37](https://tex.z-dn.net/?f=x%5Cgeq125-37)
![x\geq 88](https://tex.z-dn.net/?f=x%5Cgeq%2088)
