The answer is 8 but I’m not really sure tno
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!

B. ratio = 12:50
12/2=6 and 50/2=25
it cannot be broken down more after this is done.
so your answer is b
