Final answer:
The amount of money in a bank account is considered quantitative continuous data because it can include decimal amounts and isn't restricted to whole numbers.
Step-by-step explanation:
The amount of money in a bank account, being $512.18, is an example of quantitative continuous data. Continuous data can take on any value within a range and can include fractions and decimals. Since money can be divided down to the penny (or even smaller units in accounting practice), which is a fraction of a dollar, it is not restricted to discrete, whole number values.
This is different from quantitative discrete data, which involve counts of individual items or occurrences that can only take on specific numerical values. Examples of discrete data include the number of books purchased or the number of books sold, as these are counts of items that cannot be divided into fractions.
