Short answer

The solution of expression$\left(k+10\right)\%\text{of}200$ is 60.

Step-by-step solution

Step 1. Given Information.

It is given that $k=20$.

Step 2. Calculation.

Substitute $k$

$\begin{array}{l}\left(20+10\right)\%\text{of}200\\ 30\%\text{of}200\left[\text{add}\right]\end{array}$

Therefore, the expression is,

$\begin{array}{l}30\%\text{of}200=\frac{30}{100}\cdot 200\left[\text{writepercentageasafraction}\right]\\ =0.30\cdot 200\left[\text{multiply}\right]\\ =60\left[\text{multiply}\right]\end{array}$
