Respuesta :

Answer:

A) $9.95

Step-by-step explanation:

if you take any two ordered pairs from the table, for example:

(13, 154.5) and (24, 263.95)

then the rate of change is the (difference of the y-values)/(difference of x-values)

rate of change (also known as 'slope') = (263.95-154.5)/(24-13)

= 109.45/11 which reduces to 9.95
