Answer:
$43
Step-by-step explanation:
There are 5 lines in the ad in total.
It costs $11 for each of the first three lines which gives us:
3 x 11 = $33
There are now 2 lines left. Each additional line apart from the first three costs $5 extra. This gives us:
2 x 5 = $10
If we add the original $33 with the extra $10, we get a grand total of $43.

Subtraction of functions has the property:
f={(−4,−1),(1,1),(−3,−2),(−5,2)} has (1,1) means that f maps 1 to 1, therefore f(1) = 1
g={(1,1),(2,−3),(3,−1)} has (1,1), means that g maps 1 to 1, therefore g(1)=1
As a Result, since (f−g)(1) = f(1) - g(1), we have (f−g)(1) = 1-1=0
