$ 23.56

Step-by-step explanation

Step 1

to find the total , we need to multiply the number of pounds by the rate,

so

a)

Multiply as you would with whole numbers( ignore the decimal dot)

so


589\cdot4=2356

b)Count the total number of decimal places in your factors.


\begin{gathered} 4\Rightarrow0\text{ decimals} \\ 5.89\Rightarrow2\text{ decimals} \\ so\text{ total decimals = 2} \end{gathered}

c)Move the decimal point in the product one place to the left for each decimal place you counted.


\begin{gathered} 2356\Rightarrow2\text{ places }\Rightarrow23.56 \\ \end{gathered}

therefore, the result would be

$ 23.56

I hope this helps you
