Question

The junior high art club sells candles for a fundraiser. The first week of the fundraiser, the club sells 7 cases of candies. Each case contains 40 candles. The goal is to sell at least 13 cases. During the second week of the fundraiser, the club meets its goal. Write, solve, and graph an inequality that can be used to find the possible number of candles sold the second week.

A) 7x + 40 ≥ 13
B) 7x + 40 ≤ 13
C) 7x + 40 = 13
D) 7x - 40 ≤ 13

Answer 1

The inequality that represents the possible number of candles sold in the second week is 40x ≥ 13.

Step-by-step explanation:

To find the possible number of candles sold in the second week, we need to set up an inequality based on the goal of selling at least 13 cases. Let x represent the number of cases sold in the second week. Since each case contains 40 candles, the total number of candles sold would be 40x. The inequality that represents the goal is 40x ≥ 13.

This is because if the total number of candles sold (40x) is greater than or equal to 13 cases (13 * 40), then the goal is met.
