# How do you calculate this?

Asked by Franto Hruz, in**Education**

What are the number of days before the sum of doubling $1 each day becomes more than the sum of $100 every day? Which math equation would one use to solve for t being the number of days?

You didn't even get the question - ahahaha - we start with $1 not a penny - and what's the formula you'd be using for it? The SUM of 1+2+4+8+16+32+64+128+256+512=1,023 in 10 days at $100 a day - so $1,023 is more than $1,000 - solving for t, the number of days, the formula is 2^t > 100t or 2^t / 100t > 1 Nov 10th 2018 11:48 Edited in Nov 10th 2018 11:51 |
