Lizzy: Christine figures it would take a pint of paint to paint the front and back of 1 door in her house. She has 8 doors to paint. At the paint store, she can either buy 8 separate pints of paint for $8.00 a pint or a gallon of paint (which is the same as 8 pints) for a flat $55.00 How much money will she save if she buys the gallon of paint instead of 8 pints?.
Me: Hmmm, let me think. I think this is the detailed solution:
User
8 pints of paint cost $8.00 each so they would cost her 8 * 8 = $64.00. 8 pints of paint cost $64.00 or she could buy a gallon of paint for $55.00. If she buys a gallon, she will save 64 - 55 = $9.00. Final answer: 9.
