Problem

The cost (in dollars) for a cab ride is given by the polynomial $2+1.43 x+0.21 y$. In this context, $x$ is the number of miles driven and $y$ is the time in minutes for the ride. Part: $0 / 2$ Part 1 of 2 (a) Evaluate the polynomial for $x=13$ and $y=26$. Interpret the answer in the context of this problem. This means it costs $\$ \square$ for a $\square$ mi cab nide that lasts $\square$ min.

Solution

Step 1 :Given the polynomial $2+1.43 x+0.21 y$, where $x$ is the number of miles driven and $y$ is the time in minutes for the ride.

Step 2 :We are asked to evaluate the polynomial for $x=13$ and $y=26$.

Step 3 :Substitute the given values of $x$ and $y$ into the polynomial to find the cost of the cab ride.

Step 4 :The cost of the cab ride is calculated as $2+1.43(13)+0.21(26)$.

Step 5 :After calculating, we find that the cost of the cab ride is $26.05$.

Step 6 :Interpret the answer in the context of this problem: This means it costs \(\boxed{26.05}\) dollars for a 13 mile cab ride that lasts 26 minutes.
