Answer:
1)
Ola taxi charges a $8 flat rate in addition to $2 per mile. Paul has no more than $10 to spend on a ride.
2)
Let x be the number of miles.
Then, we have inequality:
![8x+2\leq 10](https://img.qammunity.org/2019/formulas/mathematics/middle-school/r6fgs7sz5ip2sln2bpcmfknb4vmzyb9muu.png)
Solve the inequality:
.
Subtract 2 from both the sides:
![8x+2-2\leq 10-2](https://img.qammunity.org/2019/formulas/mathematics/middle-school/j9r08qgj6s1wvvc4lmk9onl4o1dg1gnket.png)
Simplify:
![8x\leq 8](https://img.qammunity.org/2019/formulas/mathematics/middle-school/apnh0yppg839j5dmaygssu57r1rf6ye92e.png)
Divide by 8 both sides we get;
![x\leq 1](https://img.qammunity.org/2019/formulas/mathematics/high-school/mimzp7wtigjeoilfeavxoovnzx4p8249w9.png)
as shown in figure 1.
4)
From the context of the problem :
we can say that Paul can travel 1 miles or less before reaching his limit of $10.
