question about cayo

so i got bad luck on cayo and dont have any cocaine anywhere, i have 1 stack of weed in north dock and 2 stack of cash in airfield and 1 painting in office, im going with the velum plane. I want to take the painting and weed, but I want my bag to be full, so how much exact cash pieces do i need to take (I need to take the cash first because I need to fit in elite challenge 15 minute time frame)
