When working on a report for class, Catrina read that a woman over the age of 40 can
lose approximately 0.06 centimeters of height per year.
a. Catrina's aunt Nancy is 40 years old and is 5 feet 7 inches tall. Assuming her height
decreases at this rate after the age of 40, about how tall will she be at age 65?
(Remember that 1 inch = 2.54 centimeters.)
b. Catrina's 90-year-old grandmother is 5 feet 1 inch tall. Assuming her grandmother's
height has also decreased at this rate, about how tall was she at age 40? Explain your
reasoning.
HINT: CONVERT FEET INTO INCHES (1 FOOT = 12 INCHES): THEN CONVERT INCHES TO CENTIMETERS!
