To write an equation that represents the scenario where Kylie's car bill was $63, we first identify the components of Scott's charges. Scott charges a flat fee of $35 for working on the car, plus an additional $7 for each hour of work, which would be represented by \(x\) (the number of hours).
The total bill for Kylie's car can be represented as:
\[ \text{Total Bill} = \text{Flat Fee} + \text{Hourly Fee} \]
In equation form, that would be:
\[ 63 = 35 + 7x \]
This can be rearranged to find the correct form of the equation. If we subtract 35 from both sides, we get:
\[ 63 - 35 = 7x \ 28 = 7x \]
Which simplifies to:
\[ x = \frac{28}{7} \]
Thus, the equation that accurately represents the scenario is:
\[ 7x + 35 = 63 \]
So, the correct answer from your options is:
7x + 35 = 63
