It's not quite that simple

# Title Gross Theaters $/theater Budget
1 RV $16,414,767 - 3,639 - $4,510 $50m
2 U 93 $11,478,360 - 1,795 - $6,394 $15m

Basically, it cost about 1/4 of what "RV" cost, it's in half as many
theaters, and in each theater it's making 50% more. If I was funding
films, I know which one I'd rather own.
