Answer:
Let's find out!
Step-by-step explanation:
**There is 128 fl oz in a gallon**
To solve, we will try and find the unit rate of 1 fl oz of both the cost of the water and the cost of the gasoline. A unit rate is when the denominator of a fraction is 1, showing how much of something equals 1 of the denominator. For example, if the cost was $1 for 1 fl oz, the cost of a gallon of gasoline would be $128.
[tex]\frac{cost(dollars)}{fl|oz}[/tex]
[tex]\frac{1.50}{16}[/tex] ÷ [tex]\frac{16}{16} = \frac{0.09375}{1} = \frac{0.09}{1}[/tex]
[tex]\frac{3.50}{16}[/tex] ÷ [tex]\frac{128}{128} = \frac{0.02734375}{1} = \frac{0.03}{1}[/tex]
For every 1 fl oz of water, it will cost $0.09
For every 1 fl oz of gasoline, it will cost $0.03
Which costs more?
I hope this helps!
