The price of a 250$ cost increased 7% last year.The cost is now on sale for one-half off.what is the sale price .Show work
55.80 * 1.027 = 57.3066
add 2.7% (sales tax) to 100% (original cost) to get 102.7% (final cost)
102.7% is the same as 1.027
Another way to do this is to separately calculate the sales tax and add it to the original cost.
55.80 + (55.80*.027 = 1.5066) = 57.3066
And don't forget to round to the hundreds place. We are talking about money after all.
