A cell phone company charges a flat fee plus an additional charge per minute. If the graph contains the points (0,15)
and (50,90)
, what is the fee the company charges per minute? Give your answer in exact change.(1 point)
The charge per minute is $
To find the flat fee charged by the company, we can use the point (0,15). This point represents a situation where 0 minutes were used, and the charge was $15.
So, the flat fee charged by the company is $15.
To find the additional charge per minute, we can subtract the flat fee ($15) from the total charge at 50 minutes (point (50,90)) to get the additional charge for 50 minutes.
90 - 15 = 75
So, the additional charge for 50 minutes is $75.
To find the charge per minute, we can divide the additional charge by the number of minutes:
75 / 50 = $1.50
Therefore, the fee the company charges per minute is $1.50.
