In a shortage caused by a hurricane gas prices rose 15% it is now $2.80/gallon what was the price before

2.80*.15=.42

2.80-.42= 2.38

the answer is $2.38 (this was the price before)

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

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
