Answer 1

Answer:

Amount of money she will owe after 5 weeks is, $1,140

Explanation:

Unit rate defined as the rates are expressed as a quantity of 1, such as 3 feet per second or 4 miles per hour, they are called unit rates.

As per the given condition:

After 2 weeks, Emery will owe $456.

By definition of unit rate;

$\text{Unit rate per week} = \frac{\text{Amount of money}}{\text{number of week}}$                         

$\text{Unit rate per week} =\frac{456}{2} = \ 228$

Now, to find how much money she will owe after 5 weeks.

$\text{Amount of money} = \text{Unit rate per week} \times \text{number of week}$

Substitute the given values we have;

$\text{Amount of money} =228 \times 5 = \ 1,140$

therefore, after 5 weeks, she will owe $1,140
