We are given function f(a) = 1.07a for total amount including sales tax.
g(b) = b+50 total cost including delivery.
We need to write function g(f(a)).
g(f(a)) = g of f(a).
We need to substitute function f(a) in g(b) function for b.
g(f(a)) = g(1.07a) = 1.07a +50.
<h3>Therefore, g(f(a)) = 1.07a +50.</h3>
We are given mattress price a = $1125.
In order to find the total cost including delivery charges, we need to plug a= 1125 in the above function 1.07a +50.
Plugging a= $1125, we get
g(1125) = 1.07a +50 = 1.07*1125 +50 = 1203.75 +50 = 1253.75.
<h3>Therefore, total cost including delivery charges is $1253.75.</h3>

Answer:
A. For the graph, the rate of change is -2 and for the equation, it is 2.
Step-by-step explanation:
The rate of change of the line on the graph can be found by considering the rise or fall when moving one unit to the right. This line falls 2 units for each unit to the right, so its rate of change (slope) is -2.
The rate of change of the equation can be found by looking at the coefficient of x. It is 2.
So, the appropriate description is ...
For the graph, the rate of change is -2 and for the equation, it is 2.
