Explanation
The left-hand side of the equation is given: 45% of 80 is (0.45)(80) = 36. The problem then becomes: “36 is x% more than 24.” From this step, there are two possible approaches.
One approach is to translate the equation and solve:
\(36=24+\frac{x}{100}24\)
\(12=\frac{24x}{100}\)
\(x=50\)
