Answer:
The money that could be saved by drinking tap water is $165.46.
Step-by-step explanation:
Given:
Cost of 1 bottle of water = $1.00
Number of bottles consumed = 167
Volume of water used in 1 bottle = 0.132 gallons
So, volume of water used in 167 bottles = 167 × 0.132 = 22.04 gallons
Cost of 1 gallon of tap water = 7 cents = $0.07
In order to determine the money saved using tap water, we first find the cost of 167 bottles.
Using unitary method,
1 bottle cost = $1.00
167 bottles cost = Number of bottles × Cost of 1 bottle
= 167 × $1.00 = $167.00
Now, 167 dollars is spent for consuming 22.04 gallons of water.
Now, cost of 1 gallon of tap water = $0.07
So, cost of 22.04 gallons of tap water = 22.04 × 0.07 = $1.54
Therefore, the money saved by drinking tap water is given as:
Money saved = Money spent in bottles for 22.04 gallons - Money spent in tap water for the same volume
Money saved = $167.00 - $1.54 = $165.46
Hence, the money that could be saved by drinking tap water is $165.46.
The total money saved by consuming tap water is $165.46 and this can be determined by using the unitary method.
Given :
- Last year, the average American used 167 disposable water bottles.
- The cost of 1 gallon of tap water in Philadelphia is approximately 7 cents.
The unitary method can be used to determine the amount of money is saved by drinking tap water.
If the cost of one bottle is $1 then the cost of 167 bottles will be:
[tex]=\dfrac{167}{1}\times 1[/tex]
= $167
Now, if one bottle contains 0.132 gallons of water then 167 bottles contain:
[tex]=\dfrac{167}{1}\times 0.132[/tex]
= 22.04 gallons
The cost of one gallon of tap water = $0.07
Then the cost of 22.04 gallons of tap water will be:
[tex]= \dfrac{22.04}{1}\times 0.07[/tex]
= $1.54
Therefore, the total money saved by consuming the tap water will be:
= 167 - 1.54
= $165.46
