The year in which the US Civil War ended was 25 percent later than the year Christopher Columbus set sail from Spain. If c represents the year Columbus set sail, we can write the year the Civil War ended as c + 0.25c. Rewrite this expression as a single term. Rewrite the expression c + 0.25c using fractions instead of decimal numbers.

Rewrite the expression you developed in Part B as a single term with a fractional coefficient.

Are the expressions you developed in Part A and Part C the same? Why or why not?
