Answer:
second offer of $50 on first day and double it for each following day
Step-by-step explanation:
He can make more money by accepting the 2nd offer
which is $50 the first and doubling the each following day
in this way we would make 50, 100, 200, 400, 800, and so on on each subsequent days of the week adding them we get about $1550 till the 5th day itself.
which is way higher than $600 per week. Hence he should opt for 2nd option
