Answer 2

Answer: 6 kilometers

Explanation:

You have $20 to spend on taxi fee. The ride costs $5 plus $ 2.50 per kilometer. Write an inequality to determine the distance in kilometers, that, you can ride for $20. What is the maximum distance, in kilometers, you can ride for $20.

Hi, to answer this question we have to write an equation with the information given:

• Ride cost = $5 plus $2.50 per km
• Budget = $20

So, we have to add $5 and the product of 2.50 and the number of kilometers (x) to obtain the total cost.

That expression must be less or equal to the budget (20).

Mathematically speaking

5+2.5x ≤20

Solving:

2.5x ≤20-5

2.5 x ≤15

x ≤ 15/2.5

x ≤ 6 kilometers
