Answer:
The cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
Step-by-step explanation:
Let us assume this is a simple interest scenario.
Let D be the cost of desktop
Let L be the cost of laptop
Given- the laptop cost $150 more than the desktop.
So,
The total finance charge for 1 year is given by :

Substituting the value of L here, we get;

=>
=> 
=> 
=> 
D = $1750
As
So, 
L = $1900
We can check this :

=> 
=> 
So, the cost of desktop before finance charge was $1750.
The cost of laptop before finance charge was $1900.
A right triangle follows the Pythagorean theorem: a^2 + b^2 = c^2
Let’s work out the problems
1. 20^2 + 72^2 = 75^2
40 + 5184 = 5625
False
2. 40^2 + 74^2 = 85^2
1600 + 5476 = 7225
False
3. 45^2 + 60^2 = 75^2
2025 + 3600 = 5625
True
The correct answer is (45, 60, 75)
