Answer :
The variables are number of ounces and total amount of time
The relationship in equation form is y = 2.5x,
The domain is 0 to 5-oz gas tank and the range is 0 to 12.5 minutes
(a) Define the variable
To do this, we make use of the following variables
- x represents the number of ounces
- y represents the total amount of time
(b) write this relationship in equation form
From the question, we have
Rate = 2.5 minutes per ounce
When represented as an equation, we have
y = 2.5x
(c) determine the domain and range of the function in this context.
From the question, we have
Size = 5-oz gas tank
This means that the domain is 0 to 5-oz gas tank
For the range, we have
y = 2.5 x 5
Evaluate
y = 12.5
This means that the range is 0 to 12.5 minutes
