The new pair of expensive shoes you have had you eye on, originally priced at $229.50 is advertised as on sale! 40% off! Plus sales tax of 5.5%, what will you pay register?

Solution

Answer: $141.57 (As explained below)

Original price is $229.5

40% off on original price means a discount = 229.5 x 40/100 = 91.8

So, price after discount = $229.5 - $91.8 = $137.7

Add 5.5% taxes to get the price to be paid at the register = $137 + (5.5% of $137) = 137 + ((55/100) x 137) = $134 + $7.57 = $141.57
