Answer: She must knit at least 4 scarves per day to meet her goal.
Explanation:
Hi, to answer this question we have to analyze the information given, and write an equation:
Her goal is to knit at least 17 scarves, and she has already knitted 9 scarves:
Mathematically speaking:
17 -9 = 8
So, for the minimum goal she needs to knit 8 scarves more. Since she has 2 days left, we have to divide the scarves needed by the days remaining:
8/2 = 4
She must knit at least 4 scarves per day to meet her goal (the minimum).
