First, divide the total cost by the unit cost:
<span>(2y^2 + 6) / (y^2 - 1) </span>
<span>Then, if y = 3, just plug in and compute. </span>
<span>I know you can do that!

To find the price per spoon of brand A, divide the cost by the amount of spoons:
1.99 / 25 = 0.0796
Repeat this process for brand B:
3.89 / 42 = 0.0926
Brand A, at $0.08 a unit, is the better buy of brands A and B.
Hope this helps.
