Interpolated strings must be enclosed in double quotes. The Ruby interpreter will not search for interpolated values in a string if single quotes are used:
ex. p 'hello #{3}'

Notice the decimal used in the assignment of the rate variable. Decimals in programming are called Floats.

Notice the usage of the _ in the assignment of the principal variable. Ruby allows an _ to be used in numbers for better readability. Although an _ can be placed anywhere in a number, the best practice is to place them where a comma would normally be placed. (e.g. 1_000_000).

IF EXAMPLE STATEMENT
def can_buy_apple_with?(money)

    "have an apple"

end

can_buy_apple_with?(7)
