A clothing store is having a sale of 16 percent. Determine, to the nearest cent, the cost of four pairs of pants that regularly cost 23 dollars 99 cents.

In order to calculate the regular cost of the four pairs of pants, we need to multiply 23 dollars 99 by four. As the full price is equal to 95 dollars 96 cents, we can say that 100 percent is equal to 95 dollars 96 cents. As the store was having a sale of 16 percent, we need to work out 84 percent of the value. 100 percent minus 16 percent is equal to 84 percent. 84 percent as a decimal is written 0.84. This means our multiplier must be 0.84.

95.96 multiplied by 0.84 is equal to 80.6064. As we need to round this number to the nearest cent, the value is 80 dollars and 61 cents. The cost of four pairs of pants that regularly cost 23 dollars 99 cents in a sale of 16 percent off is 80 dollars and 61 cents. This is a saving of 15 dollars and 35 cents.
