Answer:
5 +2.50d ≤ 20
Step-by-step explanation:
The total cost of the ride (excluding any tip) will be the sum of the initial cost ($5) and the distance cost. The latter is the distance in kilometers (d) multiplied by the cost per kilometer ($2.50). So, the cost of the ride is ...
5 + 2.50d
We want this to be no greater than $20. Your inequality is ...
5 +2.50d ≤ 20
