Answer:
Part 1) 1.0325
Part 2) Length = 4w, Perimeter = 2(5w)
Length = 4w + 4, Perimeter = 8w + 8 + 2w
Length = 4w - 4, Perimeter = 8(w - 1) + 2w
Part 3) the amount Reagan saves after w weeks
Explanation:
For part 2, the answers are found using the perimeter formula of a rectangle (2w + 2L = P). Given that the width is "w" and the length is "4w", plug them into this formula: 2w + 2(4w) = P = 10w, which can be rewritten as 2(5w). Same method is used for the other sections.
Hope this helps!
