It is an exponential growth and the growth factor is 1.7 per day. I got this answer because after subtracting 103.70 and 61, I added the difference to 103.70, but the sum wasn't 176.29 so it has to be exponential. After figuring out that it was exponential I divided 103.70 and 61 to get 1.7 and double checked by multiplying 103.70 and 1.7 to get 176.29. Sorry this is so lengthy just wanted to make sure you understood for other questions.
