A greenhouse at Alice's nursery has 340 planters. Each planter holds 10 plants. Alice has 1,092 plants in the greenhouse. How many planters are completely empty?

1092 / 10 = 109.2 planters are used

340 - 110 = ?

To find the number of planters that are completely empty, we need to calculate the total number of plants that the planters can hold and then subtract the number of plants that are actually in the greenhouse.

First, we find the total number of plants that all the planters can hold. Since each planter holds 10 plants and there are 340 planters, the total capacity of the planters is 340 x 10 = 3400 plants.

Next, we subtract the number of plants that are actually in the greenhouse, which is 1,092.

3400 - 1092 = 2308

Therefore, there are 2308 completely empty planters in Alice's nursery greenhouse.
