Answer: $55.33
Step-by-step explanation: In order to solve this promblem, add all the monthly gas bills and take that result and divide it by the numbe rof months, to get the anerage gas bill expense
General Idea:
The exponential function will be of the form
.
When b>1, the function indicates the exponential growth.
When 0<b<1, the function indicates the exponential decay.
Applying the concept:
We are given the graph of 
, here b = 2.
The question ask the characteristic of the function when b is in the interval 
. The attached figure shows few graphs of exponential function whose b value is less than 2 and greater than 1. We can notice that graph increases at slower rate, that is change in y with respect to change in x is getting slower as we reduce the values of b less than 2 and greater than 1.
Conclusion:
"The graph will increase at a slower rate"
