Final answer:
The inequality representing Shelby's limit for the candles in the centerpieces is 2x + 4y ≤ 71, where x is the number of small centerpieces and y is the number of large centerpieces.
Step-by-step explanation:
Shelby is working on assembling centerpieces where a small centerpiece uses 2 candles and a large centerpiece uses 4 candles. Since she has a limit of 71 candles, the inequality to describe this scenario will be based on the number of each type of centerpiece she can make.
Let x represent the number of small centerpieces and y represent the number of large centerpieces. The inequality then takes the form:
2x + 4y ≤ 71
This means that twice the number of small centerpieces plus four times the number of large centerpieces must not exceed a total of 71 candles. In standard form, where terms are arranged with variables on one side and constants on the other, the inequality is rearranged as:
2x + 4y ≤ 71
