How much profit did she make on the sale? Solution 1. 2. 3. 4. 5. Pat bought something and sold it for more. To find the profit, subtract the original cost from the selling price. 450 − 329 ≈ 500 − 300 = 200 450 − 329 = 121 121 ≈ 200. Pat earned \$121 profit. In this case you could have made both 450 and 329 smaller, that is, 450 ≈ 400 and 329 ≈ 300. The approximation (\$100) would then be closer to \$121. EXAMPLE In 1850 there were 213 libraries in the United States, and they contained 942,312 books.

List the prime numbers between 100 and 120. 5. Approximate the product 45 × 789 to one nonzero digit followed by the proper number of zeros. 6. Round 49,883 to the thousands place. 7.
