    ok so basically we are asking what is 20% of 27.50 27.50*.20=5.5

    so we see that 20% of 27.50 is equal to 5.50

    ok so now our equation says 20% off of 27.50

  21. anonymous

    so meaning that we have to remove the 20% from 27.50

  22. anonymous

    so basically the 20% of 27.50 = 5.50

  23. anonymous

    and so we subtract 5.50 from 27.50 27.50-5.50= 22 so when you get 20% off the ticket the ticket will equal $22

    ya lol I hope you understand how I got that. There is a simpler method but I only can teach u it if you understand this method correctly and it makes sense in your brain. So work on a few of these problems and when you are comfortable with it I can teach u a method that is only one step

    Lets take another example. A t-shirt costs $50 dollars. There is a sale and everything in the store is 45% off? What would the price of the t-shirt be?

    So basically we would like to know what 45% of $50 is

  34. anonymous

    so we would set up our equation like this .45*50=? What is the answer?

  35. anonymous

    2250

    ,45*50=22.5 This means that 45% of $50 is $22.50 Now since it is 45% off we have to subtract that amount from the original amount 50-22.50=27.50 so The t-shirt would cost $27.50

    If there is a 20% discount, then you will have to pay 80% of the $27.50 ticket price. 0.8 * 27.50 = $22.00
