Answer:

$ 9,12

Explanation:

We first get the slope of the function;

Slope = change in credit/time

= (17.44 - 19.72 )/ (63 - 44)

= -2.28/19

= - 0.12 , its a negative slope indicating a decreasing function

To get remaining credit after 76 minutes of calls, we multiply time and slope;

= 0.12 × 76

= $ 9.12

Therefore, the remaining credit after 76 minutes will be $ 9.12
