There are 200 shirts and 100 pairs of trousers from last season that a retailer wants to get rid of. They've come up with two options, A and B, and are putting them together. Offer A is a $30 set that includes a shirt and a pair of trousers. Offer B is a $50 set that includes three shirts and two pairs of trousers. A total of 20 of Offer A and 10 of Offer B packages must be sold in order for the business to make a profit. Is there a maximum number of packets they need to sell in order to maximize profit?

Let's try defining the size of the array and create the contents of it on our own! And then, to give off a sense of excitement, let's try accessing the value of an array element in a random index position!
Let's do this fast!
Instructions:
- Create an empty character array with a size of 100.
- Use an appropriate input function for strings and store the value into the empty array.
- Input a random integer. It shall only be any integer that's less than the string's length.
- Using your understanding on accessing list elements, access and print out the array element having the index position of the inputted random integer
Input
1. A string
2. An index
Output
The first line will contain a message prompt to input the string.
The second line will contain a message prompt to input the integer which represents the index.
The last line contains the character at the index.

What mass of BaCl2 is needed to dissolve in 1.2 kg water to prepare 0.500m BaCl2 solution?
Use newton raphson method to Find an approximate root of x3
-5x+3 = 0 that lies in
[0,1]. Find the approximation to three decimal places.
- Two given lines are either parallel, skew or intersecting. (6 marks)
- Determine, if there is one, the point of intersection of the lines given by the equations
x−1/−3=y−8/6=z−3/−2 and x−8/4=y+3/−5=z−7/2
b. Give the equations of two lines that meet at the point (–1 5, 2) and which meet at right angles, but do not use that point in either of the equations. Explain your reasoning
