Answer:
The balance amount owned in six months is $ 46.8
Step-by-step explanation:
Given as :
The price of new shoes = $85
The amount paid for the shoes = $ 40
The balance amount for the shoes = $85 - $40 = $ 45
The rate of interest = 8%
the time period = 6 months = 0.5 years
From simple method
Simple interest =
![((\textrm principal* \textrm rate * \textrm time)/(100))](https://img.qammunity.org/2020/formulas/computers-and-technology/middle-school/314py5m4aqzpu2unjize61auncgqmhk3ri.png)
or, Simple interest =
![((\textrm 45* \textrm 8 * \textrm 0.5)/(100))](https://img.qammunity.org/2020/formulas/computers-and-technology/middle-school/92op7jf7ug616ih81sui4h1un12biipm6b.png)
Or, Simple interest =
= $1.8
So, Amount = Principal + Interest
or, Amount = $45 + $1.8 = $ 46.8
Hence The balance amount owned in six months is $ 46.8 Answer
