Answer:
68 plants.
Step-by-step explanation:
Let x represent the number of plants that Reuben bought from the nursery.
We have been given that Reuben bought a whole bunch of plants at the nursery the other day. Right away, five died. So number of plant left would be .
We are also told that then our dog dug up 2/9 of them. So number of plants left after dug-up would be .
Further a rabbit came and ate ½ of what was left. So number of plants left would be .
Since Reuben had only 7 plants left, so we will equate our expression with 7 and solve for x as:
Therefore, Reuben bought 68 plants at the nursery.
