Sydney needs to order some new supplies for the restaurant she works at. The restaurant needs at least 525 spoons. There are currently 335 spoons. If each on sale contains 20 spoons, which inequality can be used to determine s, the minimum number of sets of spins Sydney should buy?
A 525 ≥ 29 + 335s
B 525 ≤ 20 +335s
C 525 ≥ 20s + 335
D 525 ≤ 20s +335
The correct inequality that can be used to determine the minimum number of sets of spoons Sydney should buy is D) 525 ≤ 20s + 335.
Explanation:
- Sydney needs at least 525 spoons.
- There are currently 335 spoons.
- Sydney needs to buy sets of spoons, with each set containing 20 spoons.
- Let s be the minimum number of sets of spoons Sydney should buy.
- Sydney needs to find the minimum value of s that satisfies the requirement.
- Therefore, the minimum number of spoons Sydney should buy is 20s.
From the information given above, we can create the inequality:
Total spoons bought (20s) + Current spoons (335) should be greater than or equal to the required spoons (525):
20s + 335 ≥ 525
This can be rewritten as:
525 ≤ 20s + 335
Therefore, the answer is D) 525 ≤ 20s + 335.
