PART A: 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. PART B: Rewrite the expression C+0.25c using fractions instead of decimal numbers.

PART C: Rewrite the expression you developed in part B as a single term with fractional coefficient.
