Question

Sarah buys X pounds of almonds priced at Y dollars per pound. Jack spends the same amount of money on walnuts priced at Z dollars per pound. How many pounds of walnuts did Jack purchase? Express your answer in terms of X, Y and Z.

Answer 1

You should try to go to a grocery store and actually try this out.

However Sarah's cost = X*Y

Jack's cost will be Z * W

Where W = # of pounds of Walnuts he purchases.

The cost the same amount

X * Y = Z * W

So the # of pounds of walnuts purchased (W) equals

W = (X*Y)/Z
