The class will need to sell a minimum of 215 subscriptions at $7 each to reach their goal of $1500.
Step-by-step explanation:
You can solve this problem by setting up an inequality, with a variable, to find the number of subscriptions needed to reach their goal of $1500. Since the goal is to raise at least $1500, our expression must be ≥ 1500. Let 's' be the number of subscriptions: 7s ≥ 1500. Then, use inverse operations to isolate the variable, so divide both sides by 7: 7s/7 ≥ 1500/7 or s ≥ 214.3. Since they can't sell a partial subscription, we would need to round up to 215 total subscriptions that they would need to sell to meet their fundraising goal.
