Karate, Viola, & Art

As Miss K enters the 5th grade she has the opportunity to participate in 5th grade strings. She has selected to play the Viola. With my current finances already being tight, I have set up a go fund me account. I cannot afford to do both karate and pay for a rental/purchase plan for a Viola. Please share this every little but will help.
