Four gallons of gasoline cost $14. A customer will get
gallon for $3.50.

A customer will get
gallons for $7.00.

A customer will get
gallons for $14.00.

A customer will pay $
for 6 gallons.

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.

Step-by-step 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.

answer: $34.31

step-by-step explanation:

$11.99 x 3 = $35.97

$35.97 - 10% = $32.37

$32.37 + 6% = $34.31

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
