Answer 1

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:

$\text{Unit cost for each person} = \frac{\text{Total Cost}}{\text{Number of ticket}}$

Substitute the given values we get;

$\text{Unit cost for each person} = \frac{72.50}{10}$ = $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:

$\text{Unit cost for each person} = \frac{\text{Total Cost}}{\text{Number of weekly pass}}$

Substitute the given values we get;

$\text{Unit cost for each person} = \frac{100}{13}$ = $7.69230769.
