Anna35 [415]

Answer:

The maximum distance is 17.5 miles

No she can't make to the airport.

Step-by-step explanation:

Given the cab charges $0.8 per mile and $2 for tolls.

let the miles travelled by melissa be x.

The total charge is $(0.8*x+2)

Now given that she can spend a maximum of $16

so the inequality is

0.8*x+2\leq 16

0.8*x\leq 14

x\leq \frac{14}{0.8}

x\leq 17.5

Therefore the maximum distance she can travel is 17.5 miles

Since the distance to airport is 25 miles which is greater than 17.5 miles she cannot afford the cab.
