<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>

All you need to know is that

So, the first function grows exponentially and the second decays exponentially. The rate of growth/decay are the bases of the exponentials, which means 1.08 and 0.205
In money if you have £6.25 it is easier to write it in decimals
If you are measuring something e.g. 10.3cm long no one writes it 10 3/10 cm
Answer:
$130
Step-by-step explanation:
To find the tip you have to change the percent into a fraction first. Since percent is out of a 100, 25% is 25/100 or 1/4. Multiplying 1/4 by 520 you get 130, which is how much the coach will tip.
