Looking at the line plot, the longest number of miles is 50, and the shortest is 48 1/4.
Calculating the difference, we have:

Therefore the correct option is the third one.
Answer:
Agree
Explanation:
The given scale is:
1 in : 0.4 ft
We want to get the equivalent ft for 6 in, therefore all we have to do is cross multiplication as follows:
1 in : 0.4 ft
6 in : ??
equivalent ft = (6*0.4) / (1) = 2.4 ft
This means that:
6 in : 2.4 ft is equivalent to the given scale
Rounded would be $13.89.
0.07 * 12.98 = 0.9086 and add that to 12.89 :)
