To find out how much the computer cost last year, we can use the information that the price fell 20% this year.
First, let's calculate the original price of the computer before the 20% decrease. We can set up an equation where "x" represents the original price:
x - 0.20x = 550
Simplifying the equation, we have:
0.80x = 550
To find the value of "x," we divide both sides of the equation by 0.80:
x = 550 / 0.80
Evaluating the right side of the equation, we get:
x = 687.50
Therefore, the computer cost $687.50 last year.
