sergio has $1000 and he invests it in bitcoin. in one day, his money doubles! the next day he earned a profit of $100 and the next day he lost $500. write a number expression for this and evaluate.

Answer

Explanation:

Step1: Initial investment amount

Sergio starts with $1000$.

Step2: Amount after doubling

The next day it doubles, so the amount is $1000\times2 = 2000$.

Step3: Amount after earning a profit of $100$

The new amount is $2000 + 100=2100$.

Step4: Amount after losing $500$

The final amount is $2100- 500=1600$. The number - expression is $((1000\times2)+100 - 500)$.

Answer:

$1600$
