A fashion designer needs to stitch 40 dresses in 8 days. After 3 days, she completes only 12. How many dresses must she stitch daily to meet the deadline?
Correct answer: C. 7
- A. 4.5
- B. 5.6
- C. 7
- D. 8
Explanation
The fashion designer has a total of 8 days to stitch 40 dresses. After 3 days, she has completed 12 dresses, leaving 28 dresses to be completed in the remaining 5 days. To determine how many dresses she must stitch daily, divide the remaining dresses by the remaining days: 28 / 5 = 5.6. While 5.6 is the mathematical result, in practical terms, she needs to complete whole dresses each day. Therefore, she should aim to stitch 7 dresses per day to ensure she meets the deadline. Option C is correct because it rounds up to ensure completion within the deadline. Options A and B result from incorrect assumptions or calculations, and Option D doesn't align with the current situation.
