To find:
The expression that models the given phrase.
Solution:
Let the number of lawns mowed by Wally last week be n.
We know that, we use plus sign "+" for "more".
If Wally mowed two more lawns than he mowed last week, then the lawns mowed by the Wally this week is the sum of n and 2.
Lawns mowed this week =
The required expression for the phrase "Wally mowed two more lawns than he mowed last week" is n+2.
Therefore, the correct option is A.

<h3>How to graph the set on a number line?</h3>The set is given as:
(−∞, 0) ∪ [2, 8]
The above means that the numbers inclusive in the set are:
- (−∞, 0): All real numbers less than 0
- [2, 8]: All real numbers between 2 and 8 (inclusive)
This means that there will be a gap on the number line between 0 and 2 and from 8 till positive infinity
Having done the above illustration, next we plot the set on a number line
