Answer:
The mileage is 2,300 miles
Step-by-step explanation:
Let x be the number of miles driven.
<u>Primo:</u>
$47 per day
$0.30 per mile
$0.30x per x miles.
Total cost 
<u>Ultimo:</u>
$26 per day
$0.95 per mile
$0.95x per x miles.
Total cost 
If Ultimo charge is three times the Primo charge, then

Solve this equation:

Set each equation equal to zero.
y + 5 = 0
Subtract 5 from both sides.
y = 0 - 5
y = - 5
y - 9 = 0
Add 9 to both sides
y = 0 + 9
y = 9
y = - 5, 9
