New shoes are on sale you find a pair you like for $85 $45 with you so you pay $40 and charge the balance at 8% interest what was the balance owed be in six months

Balance amount owned in six months is $46.8

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
