A 2-liter bottle of spring water costs 2.02. A 3-liter bottle of the same water costs 2.79. Which is the better deal?
the unit cost is price/volume
so do the divisions and compare
To determine which is the better deal, we need to compare the price per liter of each bottle.
To find the price per liter, we divide the total cost of the bottle by its volume in liters.
For the 2-liter bottle:
Price per liter = Total cost / Volume = 2.02 / 2 = 1.01.
For the 3-liter bottle:
Price per liter = Total cost / Volume = 2.79 / 3 = 0.93.
Comparing the two price per liter values, we can see that the 3-liter bottle has a lower price per liter (0.93) compared to the 2-liter bottle (1.01). Therefore, the 3-liter bottle is the better deal in terms of cost per liter.
