Oscar bought shares in four different stocks. the chart below shows the changes in the stock values over the past week which stock is closest to his purchase price

150.6

all i did was i multiplied 5.02 by 30

127

whether it's diameter, or radius, i believe if i remember correctly from school, every amount has to always add up to 180. so if you take 53, and starting adding, long story short, taking 127 and adding it to 53, gives you 180.
