Answer:
A customer will get 1 gallon for $3.50.
A customer will pay $ 21 for 6 gallons.
A customer will get 4 gallons for $14.00.
A customer will get 2 gallons for $7.00.
Explanation:
This is solved using the unitary method .
Four gallons cost $ 14
1 gallon costs $ 14/4= $ 3.5
6 gallons cost = $ $ 14/4 *6= $ 21
2 gallons cost = $ 14/4 *2= $14/2= $ 7
A customer will get 1 gallon for $3.50.
A customer will pay $ 21 for 6 gallons.
A customer will get 4 gallons for $14.00.
A customer will get 2 gallons for $7.00.
This can be found out by using the direct ratio as well.
Gallons Cost
4 $14
1 x
Using cross product
x*4= $ 14*1
x= $ 14/4 = $3.5
The same can be applied to find the rest and we get the same answers.
