<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:
x≤50
Step-by-step explanation:
100-3x≥-50
subtracting 100 at both side on inequality
-100+100-3x≥--50-100
-3x≥-150
Dividing both sides by 3
-3x/3≥-150/3
-x≥--50
Adding 50 on both sides
-x+50≥-50+50
-x+50≥0
Adding x on both sides
-x+x+50≥0+x
50≥x
so,
x≤50
As you know, to get the inverse of any expression, we start off by switching the variables about and then solving for "y",
