Do you have a photo or picture of this question, I don't want to give you the incorrect answer because something was missing.
The equation that models this situation is z = 7.9y + 12.
A linear equation is a function that has a single variable raised to the power of 1. An example is x = 4y + 2.
Where:
- 2 is the constant
- x = dependent variable
- y = independent variable
From the equation given, 12 would be the constant, the independent variable would be 7.9 and z would be the dependent variable.
z = 7.9y + 12
Here is the complete question: A barrel of oil was filled at a constant rate of 7.9 gal/min. The barrel had 12 gallons before filling began. write an equation in standard form to model the linear situation.

Answer:
Step-by-step explanation:
I'm not sure if the right side is 
or 
, so I'll provide an answer for both:
Given:
Last month sales = $900
Rate of commission = 20%
To find:
How much commission (in dollars) did she earn last month?
Solution:
We have, 20% rate of commission. So, the commission for the last month is equal to 20% of last month sales $900.
Therefore, the commission for the last month is $180.
