Primo car rental agency charges $47 per day plus $0.30 per mile Ultimo car rental agency charges $26 per day plus $0.95 per mile

mario62 [17]

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 $\rightarrow$ $0.30x per x miles.

Total cost $=\$(47+0.30x)$

Ultimo:

$26 per day

$0.95 per mile $\rightarrow$ $0.95x per x miles.

Total cost $=\$(26+0.95x)$

If Ultimo charge is three times the Primo charge, then

$26+0.95x=3(47+0.30x)$

Solve this equation:

$26+0.95x=141+0.90x\\ \\0.95x-0.90x=141-26\\ \\0.05x=115\\ \\5x=11,500\\ \\x=2,300$
