Answer
Explanation:
Step1: Calculate the total cost of the new couch
First, find the tax amount for the new couch. The tax rate is 7.5% or 0.075, and the price of the couch is $1500. Tax amount = $1500×0.075 = $112.5. The cost of the couch before shipping is $1500 + $112.5=$1612.5. Then add the shipping cost of $50. So the total cost of the new couch is $1612.5 + $50=$1662.5. The new couch has a remaining life - span of 15 years. Cost per year for the new couch = $1662.5÷15≈$110.83.
Step2: Calculate the total cost of the used couch
The price of the used couch is $700 and the cost of repairs and cleaning is $200. So the total cost of the used couch is $700 + $200=$900. The used couch is 5 years old and has a remaining life - span of 15 - 5 = 10 years. Cost per year for the used couch = $900÷10 = $90.
