Finn collected

Finn collected 5 pounds of newspaper for the recycling drive. Darnel collected 4 1/2 times as much newspaper as Finn. How many pounds of the newspaper did Darnel collect?

Correct answer:

D =  22 ¹⁄₂ = 45/2 lb

Step-by-step explanation:

$$\begin{gathered} F=5\text{lb} \\ r=4\frac{1}{2}=4+\frac{1}{2}=\frac{4\cdot 2+1}{2}=\frac{8+1}{2}=\frac{9}{2}=4.5 \\ D=r\cdot F=\frac{9}{2}\cdot 5=\frac{9\cdot 5}{2}=\frac{45}{2}=\frac{45}{2}\text{lb}=22\frac{1}{2}\text{lb}=22.5\text{lb} \end{gathered}$$
