Answer:
Not much of a difference but the second bottle is the best buy
Step-by-step explanation:
1) Make sure that all corresponding units are the same.
Litres to millilitres
1.5 L x 1000 = 1500 ml
2) Find out how much you are paying for 1 ml for each bottle
a) First bottle
330 ml = $0.42
1 ml = x
330x = 0.42
x = 0.42/330
x = 0.0013
b) Second bottle
1500 ml = $1.65
1 ml = x
1500x = 1.65
x= 1.65/1500
x= 0.0011
