I don’t know if it is possible to upgrade the ram and if so how do I do it. Also what type of ram is best to get for the price to improve my system

It appears the RAM is integrated into the logic board and cannot be removed memory Standard Memory: 8GB to 16GB non-removable https://www.crucial.com/usa/en/compatibl

To compliment @mayer’s answer, this is how I immediately knew. Along with the chassis being suspiciously thin, the EMI shield over the CPU and heatsink is where the RAM is. In addition, the second red flag was a lack of DIMM module removal section in the HMM.
