The answer is athe answer is a, although your mouse was in the way so slightly difficult to read
First, let's create an equation for this problem.
($70 × 4) + $40
Now, all you would have to do is solve it using the order of operation (PEMDAS).
($70 × 4) + $40 = $280 + $40
$280 + $40 = $320
The plumber charged $320.
I hope this helps!
