Final answer:
To find the cost of a 7 mile drive, first calculate the price per mile by dividing $14.50 by 5 miles. Then, multiply that price per mile by 7 miles to get the total cost, which is $20.30.
Step-by-step explanation:
The question asks us to determine the cost of a 7 mile drive given that An uber charges $14.50 for a 5 mile drive and the price per mile is constant. First, we find the cost per mile by dividing the total cost by the number of miles. The cost per mile is $14.50 ÷ 5 miles = $2.90 per mile. Next, we multiply the cost per mile by the number of miles for the 7 mile drive, which gives us $2.90 per mile * 7 miles = $20.30 for a 7 mile drive.
