Answer:
Step-by-step explanation:
Let x represent the number of trips to the airport and
Let y represent the number of trips from the airport.
A taxi driver had 44 fares to and from the airport last Monday. This means that
x + y = 44
The price for a ride to the airport is $7, and the price for a ride from the airport is $6. The driver collected a total of $289 for the day. This means that
7x + 6y = 289 - - - - - - - - - - - 1
Substituting x = 44 - y into equation 1, it becomes
7(44 - y) + 6y = 289
308 - 7y + 6y = 289
- 7y + 6y = 289 - 308
-y = - 19
y = 19
x = 44 - y
x = 44 - 19
x = 25
