Question

I was paid $2.80 on the first day, and my salary doubled each day thereafter. I earned a total of $714. How many days did I work?

Answer 1

Go on dividing by 2 I guess the answer is 8 days

Answer 2

On dividing 714 by 2 eight times(i.e.,714/2^8 = 714/256), the result came to be 2.7890625, which is approximately equal to 2.8 .So, according to question, the no. of days you work is 8 (eight).
