Final answer:
Given the option to receive $20 per tutoring session for 5 days, which would total $100, or a starting pay of $4 that doubles each day, totaling $124 over 5 days, the better payment option would be the latter, as it earns more money overall.
Step-by-step explanation:
The subject in question is a mathematical problem involving the concepts of simple interest versus compound growth, specifically doubling. To solve this scenario, we first need to calculate the total amounts for both payment options.
Option 1 is straightforward. You receive $20 per hour for 5 days, which amounts to $20 x 5 = $100.
Option 2 involves exponential growth, doubling the previous day's pay. Here's how you calculate it:
- Day 1: $4
- Day 2: $4 x 2 = $8
- Day 3: $8 x 2 = $16
- Day 4: $16 x 2 = $32
- Day 5: $32 x 2 = $64
If you sum all the amounts for option 2, you'll have $4 + $8 + $16 + $32 + $64 = $124.
Comparing both options, option 2 ends up giving you more money ($124) compared to option 1 ($100). Therefore, Option 2 would be the better choice if your aim is to earn more money.
