Ok so first day should give u how much each stock is worth so that $1000 is proportionate to 512.49 and by day 3 at 520.56 it would give you back more money.
So the problem would look like: %281000%2F512.49%29=%28x%2F520.56%29
Cross multiply then divide by 512.49 to find x.
x=1015.7466
So basically you gained $15.75 by the third day
.
Same proportions with amazon
%281000%2F343.56%29=%28y%2F350.31%29
Cross multiply then divide by 343.56 to find y.
y=1019.6472
So basically you gained $19.65 by the third day.
