Papi Calot prepared his garden to plant potatoes. He planned to plant 7 rows of 18 plants each. But he still has a bit of room left, so he’s thinking about adding 15 additional potato plants. How many plants does Papi Calot have to buy?

How many plants did Papi plan to plant? ** Let’s first calculate the number of plants that Papi had planned: 7 rows * 18 plants/row = <<7*18=126>>126 plants
How many plants does Papi have to buy? ** Now let’s add the other plants: 126 plants + 15 plants = <<126+15=141>>141 plants. So Papi has to buy 141 plants.
