Answer:
The 40% marked up price of refrigerator is $1260.
Step-by-step explanation:
The cost price of the refrigerator = $900
Now, the mark up should be 40%
Calculating the markup on the cost price , we get
40 % of $900 = 
or, 40 % mark up = $360
Now, the Marked up cost = Cost Price + Marked up Price
= $900 + $360 = $1260
Hence, the 40% marked up price of refrigerator is $1260.
There really is no ‘best stock’ to invest in. But some good stocks to invest in are Amazon, Disney, and Apple. All are companies that have had tremendous growth and appear to still be growing. You can also go onto Yahoo finance, they will tell you whether they think the stock is over priced and you can also see the growth pattern over time.

Step-by-step explanation:
This is a piece-wise function. The three intervals we need to worry about are [0, 1), [1,2], and [2,4].
Separate the functions into their pieces and draw out the individual graphs. Place them together onto the graph within their respective intervals.
