Question 1100306: A telephone bill comprises of a standing charge of $23 per month plus a further charge of 6.8 cents per minute.
a-Using x to represent the number of units used in a quarter write down the function B(x) for the total cost of the bill in pounds over the 3 month period ?
b-Calculate the bill if the phone is used on average 148 minutes per month?

x = number of minutes

B(x) = 69 + 6.8x
(3 months, so 23 * 3 = 69 in base costs)

148 minutes a month for 3 months ---> 444 minutes total
B(444) = 69 + 6.8(444) = $3088.2
