Let's denote the amount Sara spent as \( x \).
According to the problem, Jamie spent $25 more than three times what Sara spent. This can be expressed mathematically as:
\[ 3x + 25 = 154 \]
To isolate \( x \), which represents how much Sara spent, we need to rearrange the equation.
From the provided options, the equation that correctly represents this relationship is:
\[ 3x + 25 = 154 \]
So, the correct choice is: 3 x + $25 = $154.
