Icy  river increased the price of a $1.15 cola by 15%. find the increase in price and the new price. round to the nearest cent

15%  x
100  1.15        X is your variable, your unknown number and 15% has to always be over 100 , Then you have to cross multiply and divide 100 because that is the only number basically you have to just multiply across and divide 100 to make it to the nearest cent you have to round the last two numbers after the decimal Representing money.. Hope this helps!!

Welp life just is hard
