I have calculated the daily returns in excel as attached however, I am unsure how to calculate the following homework task below, can someone assist please and thank you

Based on the 500 returns for each stock calculated in b., calculate 500 alternative scenarios for the $ value of the $350,000 investment in company A stock and the $650,000 investment in company B stock, respectively. Sum these two for each scenario to obtain 500 simulations for the $ value of your portfolio consisting of stock A and stock B.

The companies in question are APA Group and Transurban and I have also provided a small screenshot of some of the daily returns calculated with Excel.
