The transportation department recommends increasing highway tolls by 20% to raise money for road repairs. The current highway toll is $1.50. What will be the new toll after the 20 % increase?

OpenStudy (zehanz):

Welcome to OpenStudy! If you think of 20% as one fifth, there is a one fifth increase. So the new price becomes $1.50 + 0ne fifth of $1.50. Can you think of how much one fifth of $1.50 is?
