In this problem, we're told that someone paid a price of $90 .95 for a pair of nike shoes, and that this price included 7 % sales tax.
00:20
So 9095 includes the tax.
00:22
That means the actual price of the shoes, the listed price, but actually have been less than 9095.
00:29
So we want to find what is that price.
00:32
X is going to represent the actual price.
00:36
Price of shoes before tax, or not including that 7 % tax.
00:52
Since 7 equation to solve for this, we can say that 9095, the cost of shoes with tax is equal to x the cost of the shoes before tax, plus the 7 % tax.
01:08
We can represent 7 % tax by writing 0 .07 or 7 % in decimal form, multiplied by x.
01:20
What this is saying is that the total cost of 9095 is equal to the sale price x plus 7 % of the sales price or 7 % sales tax.
01:32
So now we can solve for x, the actual price of the shoes before sales tax.
01:38
If we combine 1x and 0 .07x, we get 1 .07x...
