Answer:
Balance amount owned in six months is $46.8
Step-by-step explanation:
given data
new shoes price = $85
amount paid = $40
interest rate = 8 % = 0.08
time period = 6 month = 0.5 year
solution
first we get here balance amount for the shoes that is
balance amount = $85 - $40
balance amount = $45
now we apply here simple interest method that is express as
Simple interest = principal × rate × time ................1
put here value and we will get
simple interest = $45 × 0.08 × 0.5
Simple interest = $1.8
and now we get here amount that is
Amount = Principal + Interest ..............2
put here value we get
Amount = $45 + $1.8
Amount = $46.8
so balance amount owned in six months is $46.8
