To find the total amount including a 25% tip in one step, Carter can multiply the cost of the meal by \(1.25\).
Here's why:
- The original cost of the meal is 100% of the price.
- He wants to leave a tip of 25% on top of that, which can be expressed as 0.25.
- Therefore, the total percent he is paying is \(100\% + 25\% = 125\%\).
- In decimal form, 125% is represented as \(1.25\).
So, if \(C\) is the cost of the meal, the total amount including the tip would be calculated as:
\[
\text{Total} = C \times 1.25
\]
Thus, the multiplier is \(\mathbf{1.25}\).
