Question

if 5-lb bag of sugar cost $2.49 and 10-lb bag of sugar cost $3.99 which is the better bargain? by how much

Answer 1

We must calculate the price for a pound, so we will know the best value:

`\begin{gathered} A=(2.49)/(5)=0.498 \\ B=(3.99)/(10)=0.399 \end{gathered}`

In the other words. it is better to boy 10 pounds for the costo of $3.99 since it comes out at $0.399 per pound, instead the other comes out at $0.498 per pound.
