mary bought a bike priced at $45. shipping and handling cost an additional 15% of the price. the tax charged was 10%. what was the total cost of the bike, including shipping and handling and taxes?
First you find the shipping and handling fee so thats 45x0.15=6.75 and then you take the percentage of taxes so that is 45x0.1=4.5 add those together and you get 11.25 then add that to 45 to get your total cost of everything which is 56.25.
