Rental for a telephone is 100 and the rate of calls is 30 paise per minute. Write an algebraic expression to represent the amount of bill, if n represents the number of minutes spent on calls.
The algebraic expression to represent the amount of the bill, given the rental fee of 100 and a call rate of 30 paise per minute for n minutes spent on calls, is:
\(100 + 0.3n\)
In this expression, 100 represents the fixed rental fee, and \(0.3n\) represents the cost for the calls, where 0.3 is the cost per minute in terms of rupees (30 paise is equal to 0.3 rupees), and 'n' is the number of minutes spent on calls.
