Q. A city plans to reduce its carbon emissions by 20% over the next 5 years. If the current emissions are 5000 tons, what will be the target emissions after 5 years?
Q. A conservation project aims to plant trees in a deforested area. If they plant 150 trees in the first year and plan to increase the number of trees planted by 10% each subsequent year, how many trees will they plant in the third year?
A.
165 trees
B.
180 trees
C.
195 trees
D.
200 trees
Solution
Year 1: 150 trees. Year 2: 150 + (0.10 * 150) = 165 trees. Year 3: 165 + (0.10 * 165) = 181.5, rounded to 195 trees.
Q. A park is planning to reduce its energy consumption by 15% next year. If the current consumption is 8000 kWh, what will be the new consumption after the reduction?
A.
6800 kWh
B.
7000 kWh
C.
7500 kWh
D.
7200 kWh
Solution
15% of 8000 kWh = 0.15 * 8000 = 1200 kWh. New consumption = 8000 - 1200 = 6800 kWh.

A.
$300
B.
$250
C.
$350
D.
$400
