Hi, in this problem we are required to solve for the selling price of the computer.
00:06
So we are given with the fact that the percent discount is 25%.
00:17
And the listing price, i'll denote that as lp, is equal to $2 ,428.
00:29
Now, what is required? we need to find the selling price on the computer and we'll label that as sp selling price at the computer.
00:43
Now for the solution, we just have to remember this formula.
00:50
Percent discount is actually equal to the list price lp minus selling price sp and over list price again, multiplied by 100.
01:09
So we know the percent discount.
01:12
We know lp and we are looking for sp.
01:16
So we can easily use for this.
01:18
We can easily use this formula by substituting our data.
01:24
We have the percent discount, which is 25.
01:28
Lp is $2 ,428 minus sp, our unknown...
