To evaluate $ C(1050) $ using the given function $ C(x) = 0.14x + 75 $, we substitute $ x = 1050 $ into the equation:

\[
C(1050) = 0.14(1050) + 75
\]

Calculating this:

1. Multiply 0.14 by 1050:
   \[
   0.14 \times 1050 = 147
   \]

2. Add 75 to the result:
   \[
   147 + 75 = 222
   \]

So, $ C(1050) = 222 $. This means that for 1050 kilowatt-hours of electricity used, the monthly electric bill will be $222.

Would you like to explore this function further, or do you have any specific questions?

Here are five more questions you might consider:

1. What would the electric bill be for 1500 kilowatt-hours of usage?
2. How would the bill change if the rate per kWh increased to $0.16?
3. What does a negative y-intercept imply in the context of a cost function?
4. How can the function be adjusted to reflect a discount on the first 500 kWh?
5. How does the linear nature of this function simplify understanding and calculating costs?

**Tip:** Always double-check your calculations to ensure accuracy, especially in practical applications like billing and finance.

Learn how to evaluate C(1050) using the linear function C(x) = 0.14x + 75 with a detailed step-by-step solution. This problem involves basic arithmetic and function evaluation, applicable in practical scenarios such as calculating electric bills. Suitable for students in Grades 9-12.
