Penny’s vegetable garden has nine rows of plants. Each row has eight plants. At harvest, she discovered that twelve plants were ruined. How many plants did Penny harvest from the vegetable garden?
10 points
72 plants
80 plants
12 plants
60 plants
Since Penny has 9 rows of 8 plants each, she initially had 9 x 8 = 72 plants.
However, 12 plants were ruined, so Penny was only able to harvest 72 - 12 = 60 plants.
Therefore, the answer is 60 plants.
