Answer:
B.
Step-by-step explanation:
2,400 = 7,500
First of all, you want to isolate the by dividing each side by 7,500.
After doing this, you will get
=
.
Putting this in the logarithmic form, you get
= - x
To get rid of the negative sign, you would simply multiply both dies of the equation by -1. So you would get = x.
When you simplify 2400/7500, you get 8/25, so the answer is B.
Hope this helps!
<h3>Answer: 4</h3>

Function:
Amount earned for 10 hours of work:
Step-by-step explanation:
Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.
Based on the data given in the exercise, you can identify that:
- $140 is a fixed amount.
- For each hour worked on the project, Luigi charges $25. This can be expressed as:
Then, the total amount he charges for a project is the sum of $140 and . This can be represented with the following function:
To calculate the amount of money earned for 10 hours of work, you must substitute into the function and evaluate. Then:
