A gardener plants 10 trees in 3 different rows. However, he realizes that 2 trees in each section were planted incorrectly and needs to dig them up.
In the afternoon, a total of 24 more trees. At the end of the day, 3 of the newly planted trees die from dogs peeing on them.

(10 x 3) + (-2 x 3) + 24 - 3 = ?
= 30 + (-6) + 24 - 3
= 45
Answer: There are a total of 45 trees that will survive.
