Answer: 5%.
Step-by-step explanation:
Given data:
Old price = $28,640
New price = $27,208
Solution:
Percentage of decrease
= old price - new price / old price * 100
= $28,640 - $27,208 /. $28,640 * 100
= $1432/$28,640*100
= 0.05*100
= 5%.
The percentage of decrease for the car is 5%.
This is a 3 to 2 ratio. So in this case you need 180g
Answer: The answer is (D) 
Step-by-step explanation: Given that there is a rectangle, where length of the rectangle is given by

and width of the rectangle is given by

We are to find the perimeter of the rectangle. To do so, we need to add two times length with two times breadth of the rectangle.
Therefore, perimeter is given by

Thus, the correct option is (D).
