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:

Answer: 250
40% of 350 is 140
350 minus 140 is 210
210 plus 40 = 250
X - 15 > 2x + 8 (I'm 99%) sure that is the answer
