A mobile company charges rs50 per month as rental and rs 10 per min for calls. Write down an aljebric expression to represent the cost of the bill,if m represents the no.of minutes spent on the cells
50+10m
The algebraic expression to represent the cost of the bill, assuming m represents the number of minutes spent on the calls, is:
Cost = Rental fee + (Call rate × Number of minutes)
Cost = 50 + (10 × m)
Cost = 10m + 50
To write an algebraic expression to represent the cost of the bill, we need to consider two components: the monthly rental charge and the charge for the number of minutes used on the calls.
Let's define the variables:
m = number of minutes spent on calls
The monthly rental charge is a fixed amount of Rs 50. Therefore, the expression for the rental charge is simply 50.
The charge for the number of minutes used on the calls is Rs 10 per minute. Multiplying the number of minutes (m) by Rs 10 gives us the charge for the calls.
So, the algebraic expression to represent the cost of the bill is:
Cost = 50 + 10m
