A bicycle is marked 40% the original price of $150. Is is then taxed at 7 1/2%. What is the final total cost of the bicycle

Answer: $64.5

Step-by-step explanation:

First let's do 40% of 150 (40%=4/10) : 4/10*150=60

The price of the bike is $60

7.5%=7.5/100, however we cannot have a decimal in a fraction so we multiply by 2/2 and get 15/200.

Next let's multiply 60 by 15/200: 6*15/200=4.5

Then we add 60 which is the price of the bike, with 4.5, which is the tax to get the total of $64.5

Answer:$96.75
