The scale used in map was 1 cm = 15 km.

Step-by-step explanation:

Given,

Distance between two cities on map = 3 centimeters

Actual distance between cities = 45 kilometers

Ratio of distance on map to actual distance = 3:45

Both are multiples of 3, therefore, dividing by 3

$\frac{3}{3}:\frac{45}{3}$

$1:15$

The scale used in map was 1 cm = 15 km.

20000*0.45 = 9000 in the bond
20000*0.15 = 3000 in the CD
20000*0.20 = 4000 in stocks
20000*0.029 = 580 in savings

A=9000(1 + 4.35%)^3 = 10,226.33
A=3000(1 + 2.90%)^3 = 3,268.64
A=4000 (1 + 8%) x (1 - 4%) x (1 + 6%) = 4,396.03
A=580(1 + 4.35%)^3 = 4,545.04
Total value = 22,436.04
Gain = 22,436.04 - 20,000 = 2,436.04
