It's called a business subscription model.
Answer:
$150
Explanation:
The Warranty Expense account is a liability account and it must include all the estimate costs associated to the merchandise sold:
100 radios were sold and the company estimates to replace 5% or them = 100 x 5% = 5 radios
the cost of replacing 5 radios = 5 radios x $30 per radio = $150
You would have to invest 97,222
97222*6=5833.32 + 97222= 103055.32 Year one
103055.32*.06= 6183.32 = 109238.64 Year two
109238.64*.06= 6554.32= 115792.96 Year three
115792.96*.06= 6947.58 = 122740.54 Year four
