(when working on a report for class, Catrinaś read that a women over the age of 40 can lose approximately 0.06 centimeters of height per year.)

a. Catrinaś aunt Nancy is 40 years old and is 5 feet 7 inches tall. Assuming her height decreases at this rat after the age 40, about how tall will she be at age 65? ( remember that 1 inch= 2.54 centimeters.)

b. Catrinaś 90-year-old grandmother is 5 feet 1 inch tall. Assuming her grandmotherś height has also decreased at this rate, about how tall was she at the age 40? Explain your reasoning.

Please help me on this one :(
