<span>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%</span>
Answer:
44cm^2
Step-by-step explanation:
We work with area for rectangles using the face of the longer length first as this is the awkward length the perpendicular side to the easy calculation of the square and sits perpendicular to the square.
We choose the longer length and plug in and choose one of the two calculation answers.
11 x 4 = 44
11 x 6 = 66
We see the answer is 44cm^2, so we choose this one.
The best way to answer this question is to set up the first sentence as a ratio of large bandages to total bandages. You would write 5 large bandages to 7 total bandages to 7 total bandages. Then you would make this equivalent to x number of large bandages to 60 total. It would look like this 5:7 = x:60. You could use cross products to multiply 60 by 5 to get 300. 7 times x also should equal 300. Unfortunately, this example will not leave us with a whole number of bandages, but 300/7 is a repeating decimal or a mixed number (42 6/7 large bandages).
