How to Solve
Given: Cost of 1 sparkling bottle last week = $1.69
This week's cost of 4 bottles is $5.
To find: The cost of 1 bottle.
For finding how much we pay less this week, we have to subtract the cost of 1 sparkling bottle this week from the cost of 1 sparkling bottle last week.
Generally, they are $1.69 apiece, and this week they are 4 for 5$
This means that this week, they are $1.25 apiece, meaning you spend less, by about $0.44
This weeks is cheaper by 44 cents
