Question

Susana bought a laptop for $500. It was marked $50 off because it was out of the box and slightlly scratched. She also got 20% student discount, which was taken off the original price. What was the original peice of the laptop? Write and solve an equation to answer the question

Answer 1

Answer: 500*20%=100-50=50

Explanation:

500*20%=100-50=50

Answer 2

20% of $500 = 100$ so we take off 100.

And we take off $50 because it was out of the box and slightly scratched.

So result is $500 - $100 = $400
$400-$50 = $350

Answer = $350

Equation:
Let’s say
500=X
100=Y
50=Z
And answer = A

A=X-(Y-Z)
