what type of example can you give me using the 3 quantities (amount, base and rate)given as to how to solve each when one is missing?

Sure! Let me give you an example of how to solve for each quantity (amount, base, and rate) when one is missing.

1. Finding the Amount:
Let's say you want to find the amount when you know the base and the rate. The formula to calculate the amount is: Amount = Base * (1 + Rate). Now let's use an example: If the base is $500 and the rate is 5%, you can find the amount by substituting these values into the formula: Amount = $500 * (1 + 0.05) = $525.

2. Finding the Base:
Suppose you want to find the base when you know the amount and the rate. The formula to calculate the base is: Base = Amount / (1 + Rate). Let's use an example: If the amount is $750 and the rate is 10%, you can find the base by substituting these values into the formula: Base = $750 / (1 + 0.10) = $681.82.

3. Finding the Rate:
If you want to find the rate when you know the amount and the base, you can use the formula: Rate = (Amount / Base) - 1. Let's say the amount is $400 and the base is $300. By substituting these values into the formula: Rate = ($400 / $300) - 1 = 0.3333 (or 33.33%).

These examples demonstrate how to solve for each of the three quantities (amount, base, and rate) when one of them is missing. By using the appropriate formulas and substituting the known values, you can find the missing quantity in various financial calculations.
