Question

A 1-liter bottle of orange juice used to cost $2.85 at a food market. Its price has increased; the new price is 110 percent of the original price. What is the new price of the juice? Round your answer to the nearest cent.

Answer 1

To solve this you need to change the % value into a decimal value.

Remember when you calculating percents you do a division and then the last step to change the decimal into a percent is to multiply by 100.

SO, to change the percent back into a decimal value you need to divide by 100.

 

110% ==>>  110% / 100 = 1.10

 

Now take the old cost and multiply by 1.10, then round off to the nearest cent.
