How did we arrive at this assertion?

To determine Lorenzo's new balance using a calculator, follow these steps in the correct order:

1. Enter the initial checkbook balance: Press the keys 118.00.

2. Subtract the amount of the first check: Press the subtraction key (-) followed by 9.00.

3. Subtract the amount of the second check: Press the subtraction key (-) followed by 84.25.

4. Add the amount of the deposit: Press the addition key (+) followed by 95.00.

5. Calculate the new balance: Press the equals key (=).

How are 55:100 and 66:120 equivalent?

Answers

They are both equal to 11/20. 55/100 can both be divided by 5. 55/5 is 11 100/5 is 20 so 11/20. 66/6 is 11 and 120/6 is 20, so 11/20.

What would my final balance be if i put $650 in the bank for 60 months with an interest rate of 6%?

Answers

Your final balance would be $2,340.

I = Prt
Percent (6%) x rate (650) x time (60 months) = 2,340

6% = 0.06

0.06 x 60 x 650 = 2,340

Final answer:

You would end up with approximately $871.89 in your bank account after investing $650 for 60 months at an annual interest rate of 6%, if the bank compounds the interest yearly.

Explanation:

In this case, we are calculating the compound interest over a certain period. The formula for compound interest is:

P = C * (1 + r/n)^(nt)

C is the initial deposit (the principal). In your case, this is $650.
The interest rate (r) is 6%. To use this in the formula, we need to convert it to decimal form by dividing by 100, so r = 0.06.
n is the number of times that interest is compounded per unit t. Since it's not stated in the question, we'll assume it is once per year.
t is the time the money is invested for in years. Converting your 60 months to years gives t = 60/12 = 5 years.

Substitute the values into the formula:

P = $650 * (1 + 0.06/1)^(1*5)

Applying mathematics, we get an approximate final balance of $871.89
