Find a number you can multiply by the bottom of the fraction to make it 10, 100, or 1000 and multiple both top and bottom by that number then write down just the top number putting the decimal point in the correct spot.
Answer:
my answer is in this picture
You do -2 plus 4. Answer is 2.
Then do 2-(-2) which is 0.
The final answer is 2.
To represent this scenario, you will look at what is happening mathematically and represent it.
Beginning with 5, this will double each day, so 5 x 2 is the deposit.
Then, this amount will double, so (5 x 2) x 2 is the deposit.
Next this will double, and so on.
What is happening is that it is always doubling the previous day's deposit, so x 2 x 2 x 2, etc... you will use exponents to show the number of days that it doubled.
y = 5 x 2^x
