Answer:
What is part 1?
Step-by-step explanation:
Some useful relations and identities:



By the first relation, we have

Applying the two latter identities, we get

We can apply the third identity again:

and this is probably as far as you have to go, but by no means is it the only possible solution.
Answer: $40.95
Step-by-step explanation:
65 times 40%=26
So 40% off is 26 dollars off
The price is $39
Then when you add the sales tax by doing 39 times 5%, you see that the sale tax is $1.95
39+1.95= $40.95 for the jacket
It's a bit tedious, but it's just a bunch of factoring and manipulation.
