Michelle took a taxi home from the airport. The taxi fare was $2.25 per mile, and she gave the driver a tip of $5. Michelle paid a total of $45.50. The equation 2.25x + 5 = 45.5 can be used to find the distance in miles (x) between the airport and Michelle's home.
How many miles is it between the airport and Michelle's home?
A. 16 miles
B. 17 miles
C. 18 miles
D. 19 miles
First, we need to solve the equation 2.25x + 5 = 45.5
Subtract 5 from both sides:
2.25x = 40.5
Divide by 2.25:
x = 18
Therefore, it is 18 miles between the airport and Michelle's home.
The answer is C. 18 miles.
