Gerry is looking to buy a new car and finds one she likes for $1000. It means 100% corresponds to $1000.
There is 15% off. It means, she can save 15% of the total value of the car. We need to calcualte the amount of money that she can save taking the 15% off (O)
O = $1000 * (15%)
O = $1000*(15/100)
O = $1000*(0.15)
O = $150.
100% corrsponds to $1000, and 15% corresponds to $150.If she takes 15% off, we can conclude that she can save $150.
