    Answer:

    10 pounds of potatoes would cost $15.

    Step-by-step explanation:

    Set up proportion.

    4/6=10/x

    simplify 4/6 into 2/3,

    2/3=10/x

    cross product,

    2*x=3*10

    2x=30

    x=30/2

    x=15

    lemme just add some to the great reply above,

    \begin{array}{ccll} lbs&\$\\ \cline{1-2} 4&6\\ 10&x \end{array}\implies \cfrac{4}{10}=\cfrac{6}{x}\implies 4x = 60\implies x = \cfrac{60}{4}\implies x = 15
