To find your earnings per hour, you need to solve the equation given. The equation \(40y = 280x\) describes the relationship between hours worked (x) and earnings (y). Here, you worked 40 hours and made $280.
To find your hourly rate (y), which is your earnings per hour, you can manipulate the equation as follows:
1. Substitute \(x\) with 1, since we are looking for the amount earned in one hour:
\[
40y = 280 \cdot 1
\]
\[
40y = 280
\]
2. Now, divide both sides by 40:
\[
y = \frac{280}{40}
\]
\[
y = 7
\]
This means your earnings per hour is **$7.00**.
So the correct response is:
**$7.00**
