Question

Eve knits scarves for her online store. This week she has already knitted 9 scarves. There are 2 days left in the work week. She set a goal for herself to knit at least 15 scarves and at the most 19 scarves this week. Eve wants to know how many scarves she should knit each day to meet her goal.

Which inequality represents the given situation?
A.
15 ≤ 2x − 9 ≥ 19
B.
15 ≤ 2x − 9 ≤ 19
C.
15 ≥ 2x + 9 ≥ 19
D.
15 ≤ 2x + 9 ≤ 19

Answer 1

B. 15 ≤ 2x - 9 ≤ 19

Explanation:

Eve has already knitted 9 scarves, so we subtract 9 from the total she wants to knit.

She has 2 days left in the work week, so she needs to knit a certain number of scarves each day, represented by 2x.

She set a goal to knit at least 15 scarves and at most 19 scarves, which is why we have the inequalities 15 ≤ 2x - 9 ≤ 19.

So, option B correctly represents the situation where Eve wants to knit between 15 and 19 scarves this week by knitting a certain number of scarves each day for the remaining 2 days.
