You have \$20$20dollar sign, 20 to spend on taxi fare. The ride costs \$5$5dollar sign, 5 plus \$2.50$2.50dollar sign, 2, point, 50 per kilometer. Write an inequality to determine the distance in kilometers, ddd, you can ride for \$20$20dollar sign, 20. What is the maximum distance, in kilometers, you can ride for \$20?$20?

The answer is 8 kilometers.

Step-by-step explanation:

Let X be the total cost of the taxi fare and Y be the distance traveled. If the taxi fare costs $5, $2.5 for each kilometer, we can write an inequality such as

X = 2.5 x Y.

If the total amount of money for the ride is $20, when we put it into the inequality, 20 = 2.5 x Y

                 Y = 20 / 2.5 = 8.

For $20 you can ride for a maximum distance of 8 kilometers.

I hope this answer helps.

Equation: 5+2.5d≤20

Kilometers: 6
