Step-by-step explanation:
(i) the area of the floor is 30m² (6m · 5m)
(ii) the perimeter of the floor is 22m (6m + 5m + 6m + 5m)
(iii) the area of the walls is:
24m² (for the 6m by 4m walls)
20m² (for the 5m by 4m walls)
88m² in total total
Answer:
<h3>Car A</h3>
- Initial price = $30000
- Initial depreciation = 20%
- Further yearly depreciation = $2000
<u>The equation to reflect the above:</u>
- A(t) = 30000 - 0.2*30000 - 2000t ⇒
- A(t) = 24000 - 2000t
<h3>Car B</h3>
- Initial price = $25000
- Initial depreciation = 10%
- Further yearly depreciation = $1500
<u>The equation to reflect the above:</u>
- B(t) = 25000 - 0.1*25000 - 1500t ⇒
- B(t) = 22500 - 1500t
