Question 32271
Hello!
The cost of the taxi ride should be expressed as follows:

{{{C(X) = 2.95 + 1.65X}}}

where X is the number of miles. Notice that when the number of miles is zero, you're chard 2.95 ("There is a fixed charge of 2.95 as soon as you get in the taxi"), and then, for each 1 extra 'X' (one mile), the cost rises by 1.65 ("a charge of 1.65 per mile is added").

In order to find the cost of the 5-mile ride, we simply set X=5 and find C:

{{{C(5) = 2.95 + 1.65*5 = 11.20}}}


I hope this helps!
