Ann took a taxi home from the airport. The taxi fare was \$2.10$2.10 per mile, and she gave the driver a tip of \$5$5. Ann paid
Ivahew [28]

Answer:

2.10x+5=49.10

Step-by-step explanation:  

We have been given that Ann took a taxi home from the airport. The taxi fare was $2.10 per mile, and she gave the driver a tip of $5. Ann paid a total of $49.10.

Let x be the distance in miles between airport and Ann's home. The fare per mile taxi ride is $2.10, therefore, the fare for x miles of taxi ride will be 2.10x.

We can see that $5 will be constant value for our equation as it will remain same. 2.10x+5 will be total amount paid by Ann for x miles of taxi ride including tip.  

We can write an equation to determine the distance between airport and Ann's home by equating fare of x miles plus tip given by Ann's to driver with total amount paid by Ann.

2.10x+5=49.10

Therefore, an equation representing the distance in miles between airport and Ann's home will be 2.10x+5=49.10.
