Answer:
$12579.84
Step-by-step explanation:
Anna deposited $10,000 into an account three years ago.
The first year she earned 12 percent interest
Interest = 12% of 10000 =![\frac{12}{100} \times 10000=1200](https://tex.z-dn.net/?f=%5Cfrac%7B12%7D%7B100%7D%20%5Ctimes%2010000%3D1200)
Amount at the end of first year = 10000+1200 = 11200
The second year she earned 8 percent interest
Interest = 8% of 11200 =![\frac{8}{100} \times 11200=896](https://tex.z-dn.net/?f=%5Cfrac%7B8%7D%7B100%7D%20%5Ctimes%2011200%3D896)
Amount at the end of second year = 11200+896 = 12096
The third year she earned 4 percent interest.
Interest = 4% of 12096 =![\frac{4}{100} \times 12096=483.84](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B100%7D%20%5Ctimes%2012096%3D483.84)
Amount at the end of third year = 12096+483.84 = 12579.84
Hence she have $12579.84 in her account today

Answer:
Amount required = 2,217,600
Step-by-step explanation:
Dimensions of the rooms are as follows;
Room 1; 9 feet × 12 feet
Room 2; 14 ft × 16 ft
Room 3; 12 ft × 14 ft
Perimeter of rooms;
P1 = 2(9 + 12) = 42 ft
P2 = 2(14 + 16) = 60 ft
P3 = 2(12 + 14) = 52 ft
Total perimeter; P = 42 + 60 + 52 = 154 ft
Height is 90 ft.
Thus, total area is;
A = 154 × 90
A = 13860 ft²
Rate of painting is 160 per Sq.ft.
Thus amount to paint entire area = 160 × 13860 = 2217600
