Answer:
6 = W + 2
Explanation:
The reason is since the hangar balance is "balanced" and there are six units on the left side and only 2 on the right (minus the variable weight), that means that the left weight is equal to the right and therefore 6u=w+2u.
Eqn (1)*3: 15x + 6y = -9 -> Eqn (3)
Eqn (3) - Eqn (2): 12x = -15
x = -5/4 = -1 1/4
Eqn (2): -15/4 + 6y = 6
6y = 9 3/4
y = 1 5/8
x = -1 1/4
y= 1 5/8
<u>Answer</u>:
The resale value after three years = $ 632.8125
<u>Explanation</u>:
Given the laptop purchase for $1500
Therefore, the cost price = $1500
According to the question, the resale value decreases by 25%,
Then after three years, the resale value is
Resale Value = 
Substituting the values,
Resale Value = 
Resale Value = 
Resale Value = 
Resale Value = $632.8125
Therefore, the resale value after three years = $ 632.8125
