  10. Find the percent of increase or decrease: • The price of a sweater decreased from $29.99 to $24.49.

  11. Find the percent of increase or decrease: • The price of a sweater decreased from $29.99 to $24.49. • The price of gas in 1999 was $0.99 a gallon and is now $2.69 a gallon.

  12. Greatest possible error:

  13. Greatest possible error: • One half the measuring unit.

  14. Greatest possible error: • One half the measuring unit. • When measuring height you go to the nearest inch, so the greatest possible error is 0.5 inches.

  15. Greatest possible error: • One half the measuring unit. • When measuring height you go to the nearest inch, so the greatest possible error is 0.5 inches. • Percent error:

  16. Greatest possible error: • One half the measuring unit. • When measuring height you go to the nearest inch, so the greatest possible error is 0.5 inches. • Percent error: • Ratio of greatest possible error to measurement.

  17. Percent error: • Suppose you measure a CD and record its diameter as 12.1 cm. Find the percent error in your measurement.

  18. Percent error: • Suppose you measure a CD and record its diameter as 12.1 cm. Find the percent error in your measurement. • Since the measurement is to the nearest 0.1cm, the greatest possible error is 0.05cm.
