These are estimation problems, so they should not be worked with a paper and pencil or with a calculator. For example, with Problem 13 think: 20% off 1,256.95 is about 20% of $1,000 = $200 or with Problem 15 think: $85.45 is about $100 and 7% of $100 = $7 so the total should be about $85.00 + $7.00 = $92.00.
