Answer: The number of miles would be no more than 350 miles.
Step-by-step explanation:
Let the number of days be 'd'.
Let number of miles be 'm'.
Cost of each day = $75
Cost of each mile = $0.50
Total amount must be no more than $400.
According to question, it becomes,
[tex]75d+0.50m\leq 400[/tex]
Since the number of days = 3
So, we put the value of days in the above equation:
[tex]75\times 3+0.50m\leq 400\\\\225+0.50m\leq 400\\\\0.50m\leq 400-225\\\\0.50m\leq 175\\\\m\leq \dfrac{175}{0.50}\\\\m\leq 350[/tex]
Hence, the number of miles would be no more than 350 miles.
