Ratio problems

For this task, I had to solve a word problem about ratios.

At the start, it was quite complicated so I had to use simultaneous equations to create a single equation that would find out the price the present. At first, I created equations that would find out the price of the present and Sotaro's and Anthony's original savings. Next, using simultaneous equations, I combined the three equations into one to find out the price of the question. After that, using the price of the present and the other two equations, I found out Sotaro's and Anthony's original savings. If I were to do this again, I would round up the numbers so that it would be easier to solve the equations.

Relative frequency- Dancing man code

For this project, I had to work in groups of four in which my group members are Holly, George and Anthony. We had to find out what the encrypted text originally was and which literary piece it came from. Even though at the start we didn't really work well together, but at the end we found out many interesting things. Eventually we found out that the encrypted text was from Alice in the wonderland  by Lewis Carroll.
