A gardener planted 300 flowers. He estimates that 75% of them will bloom. How many flowers does he estimate will bloom? After a month, he finds that only 180 flowers bloomed. How does this compare to his estimate?

• The gardener estimated 300 flowers would bloom, but only 180 actually bloomed, which is 120 fewer than his estimate.

• The gardener estimated 225 flowers would bloom, but only 180 actually bloomed, which is 45 fewer than his estimate.

• The gardener estimated 150 flowers would bloom, but 180 actually bloomed, which is 30 more than his estimate.

• The gardener estimated 225 flowers would bloom, and 225 actually bloomed, which is equal to his estimate.
