Using the results from parts D through G, write an expression that represents the number of years elapsed between the disappearance of the Greek city of Helike and the end of the US Civil War. Write the expression in terms of c and w. Then solve the expression to find out how many years separate these two events. Rewrite the equation from Part A by factoring the side that contains the variable r.

Solve the two previous equations for r. What value does each equation give for Raul’s age? Are the two values the same?

Raul’s grandfather is Miguel, and Raul’s sister is Paula. Raul’s age is the same as his grandfather’s age minus 60 times the age of his sister. Miguel is 65 years old. Using the results from Part C, write an equation to find Paula’s age, p (in years).

Rewrite the equation from Part D by factoring the side that contains the variable p.

Solve the equation for p to find Paula’s age. Express her age (in years) as a fraction.

How many months old is Paula?
