Show both decimal places (5.06).
1 answer:
a. the cost of a call for six minutes is 0.70.
b.the cost of a 14-minute call is 2.62.
c.the cost of a 9 ½2-minute call is 1.66.
<h3>How to find the cost of each call ?</h3>given that
rate schedule for an m-minute call from any of its pay phones 0.70.
c(m) = 0.70 when m<=6
c(m) = 0.70+ 0.24(m-6) when m>6 & m is an integer
c(m) = 0.70+0.24((m-6)+1) when m>6 & m is not an integer.
a. to find the cost of a call for six minutes.
already given that c(m) =0.70 when m=6.
Therefore, the cost of a call for six minutes is 0.70.
b. to find the cost of a 14-minute call.
according to given information
Therefore,the cost of a 14-minute call is 2.62.
c.to find the cost of a 9 ½2-minute call
according to given information
Therefore,the cost of a 9 ½2-minute call is 1.66.

Hey there :)
We can find the common difference here as it is an arithmetic sequence.
The common difference between each term is:
We can find the unknown term by:
{easier way in this example}
OR
by the formula for finding the nth term
a₆ =
{a₆ because it is the 6th term to be found, (6-1) the nth term minus 1}
a₆ =
However this way is not essential here as the previous term is given.
