Answer:
The answer is t=2m+5
Explanation:
because she is painting 2 every month so 2*m and she started with 5 so you have to add the 5.
After 1 month she would have 7 paintings because 2*1=2 and add the 5.
After 2 months she would have 9 paintings becuase 2*2=4 and add the 5.
This would continue with each month.
