Answer:
The mileage is 2,300 miles
Step-by-step explanation:
Let x be the number of miles driven.
Primo:
$47 per day
$0.30 per mile [tex]\rightarrow[/tex] $0.30x per x miles.
Total cost [tex]=\$(47+0.30x)[/tex]
Ultimo:
$26 per day
$0.95 per mile [tex]\rightarrow[/tex] $0.95x per x miles.
Total cost [tex]=\$(26+0.95x)[/tex]
If Ultimo charge is three times the Primo charge, then
[tex]26+0.95x=3(47+0.30x)[/tex]
Solve this equation:
[tex]26+0.95x=141+0.90x\\ \\0.95x-0.90x=141-26\\ \\0.05x=115\\ \\5x=11,500\\ \\x=2,300[/tex]
