Answer
Figure This!
 

Quick Answer:
If you are working the entire week, the doubling method earns you more money.

 

Complete Solution:
If you are paid $20 per day for seven days, the you earn $20 × 7 or $140. If you are paid $2 the first day and your salary doubles every day for the next six days, then you earn $2 + $4 + $8 + $16 + $32 + $64 + $128, or $254. The second scheme earns you more money by the end of the week.
