Marissa and Jarod plan to purchase DVD players with a regular price of $199.99. The DVD players are on sale for 25% off.
=> Marissa starts by calculating 25% of $199.99.
25% of 199.99 dollars
25% = 0.25
199.99 * .25 = 49.99 dollars
=> Jarod calculates 75% of $199.99.
75% = .75
199.99 * .75 = 149.99 dollars
Do both methods result in the same sale price? Explain.
The answer is NO. Marissa calculated for the discount which is 25% while Jarod calculated for the discounted price which is 75%

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
