Final answer:
To find out how much money Ms. Porter's class still needs to collect for the fruit baskets, subtract the amount they have already collected from the minimum amount they need. The class still needs to collect at least $35.
Step-by-step explanation:
To find out how much money Ms. Porter's class still needs to collect, we can subtract the amount of money they have already collected from the minimum amount they need to buy the fruit baskets. Let's represent the money they still need to collect as 'x'. The inequality would be: x ≥ $120 - $85. Simplifying the inequality, we get x ≥ $35.
