Hello!

First we need to find 30% of our laptop. To do so we multiply by 0.3

550(0.3)=165

Now we subtract this cost from our original.

550-165=385

Therefore, the sale price would be $385.

I hope this helps!

If coupon is 30% off that means that a laptop will have the sale price 100%-30%=70% of a regular price.

So, we need to find 70% of $550.

70% = 0.7

70% of $550 is 0.7*$550=$385.

The sale price of the laptop is $385.
