A cellular phone service provider charges $45 per month and $0.08 per minute of airtime. Enter the linear model that represents the monthly charge, c, as a function of t, the airtime used, in minutes.

C(t)=0.08t+45

Step-by-step explanation: t is the independent variable and c is the dependent variable. The rate/slope is 8 cents per minute, or $0.08, and the cost just to get service, or y intercept l, is $45

0.47metres per minute

Step-by-step explanation:

you would minus t 5 from 3 which would be 1.34- 0.87 which equals 0.47
