Question

Marketa bought 3.5 pounds of walnuts for $24.50. Approximately how many pounds of walnuts can Marketa purchase for $2?A) .28lbB) .5lbC) .35lbD) .43lb

Answer 1

Marketa bought 3.5 pounds of walnuts for $24.50

To determine how many pounds of walnuts she can purchase with $2, assuming that the price per pound is proportional, you can use cross multiplication:

$24.50______ 3.5pounds of walnuts

$2.00 ______ x pounds of walnuts

Both relationships are at the same ratio so that:

`\begin{gathered} (3.5)/(24.50)=(x)/(2) \\ x=2((3.5)/(24.50)) \\ x=2\cdot(1)/(7) \\ x=(2)/(7) \\ x\approx0.285\approx0.29 \end{gathered}`

She can buy 0.29 pounds of walnuts with $2
