IceJOKER [234]

Answer:

The original cost is $350

Step-by-step explanation:

Let's assume

original cost of computer is x

There is a 10% off sale on laptop computers

now, we are given

someone saves $35 on a laptop

so, we can set them equal

and then we can solve for x

0.10x=35

we can divide both sides by 0.10

and we get

x=350

So,

The original cost is $350
