Answer:
Unit rates defined as the rates are expressed as the quantity 1 such as 2 miles per hour or 5 metre per second.
We have to find the unit cost for each person.
Given that Hailey buys a 10-trip train ticket for $72.50
By definition of unit rate:
[tex]\text{Unit cost for each person} = \frac{\text{Total Cost}}{\text{Number of ticket}}[/tex]
Substitute the given values we get;
[tex]\text{Unit cost for each person} = \frac{72.50}{10}[/tex] = $7.250.
Also, it is given that Kimberly buys an unlimited weekly pass for $100 and uses it for 13 trips during the week.
By definition of unit rate:
[tex]\text{Unit cost for each person} = \frac{\text{Total Cost}}{\text{Number of weekly pass}}[/tex]
Substitute the given values we get;
[tex]\text{Unit cost for each person} = \frac{100}{13}[/tex] = $7.69230769.
