Can some one me i will give extra points

$12.7 is the final cost to the nearest cent

1.) The item costs $30. Let's find the sale price. Since the item is on sale for 15 percent, you have to multiply $30 (cost) by 15 percent. $30 (0.15)= $4.50.

2.) Now, let's move on to the next part of the problem. Now, we can use the sales price for finding the sales tax. You have to multiply $4.50 (sales price from step one) by 8.2 percent (sales tax). $4.50 (0.082)= $0.369.

*Now remember: you always multiply the sales price by the sales tax, not the original price by the sales tax, unless instructed to do so*

3.) Let's round the answer to the nearest cent. $0.369 is about $0.40 (round-up).

4.) The item's final cost is about $0.4.

Hope this helped. ^^

In the first triangle 80+20+p=180 (since sum of all angles of a triangle is 180)so p= 80also in second triangle 55+45+q=180 (since sum of all angles of a triangle is 180)so q=80so we can conclude that p=80 degrees q=80 degrees so p=q=80 degreeshence option b is correct
