Assessment Guide Houghton Mifflin Harcourt Publishing CompanyAG333Answer KeyChapter 3 TestPage 1 Houghton Mifflin Harcourt Publishing CompanyAG49Answers will vary. Possible answer: I think theestimate using the compatible numbers is a betterestimate. When rounded numbers are used to findan estimate, each factor becomes greater than theactual factors, so the product will be an overestimate.When compatible numbers are used, one estimatedfactor was 2 less than the actual factor and the otherestimated factor was 2 more than the actual factor, sothe estimate should be close to the actual product.Which do you think is the better estimate? Explain.Part CThe total cost would be about 500.20 25 500Use compatible numbers to estimate the total cost of the field trip.Part BThe total cost would be about 600.20 30 600Round each factor to estimate the total cost of the field trip.Part AMr. Burn’s class is taking a field trip to the planetarium.
