Aschool bus uses 34 of a tank of gas to drive back and forth to school in a week with 5 school days. how much gas does the bus use to drive back and forth to school in a week with 4 school days? write your answer in simplest form.

  I am assuming Michael's interpretation is correct, that you want to find how much gas is used in 4 days knowing how much is used in 5 days.  Set up a simple proportion and solve it:

 3/4 tank → 5 days

 x tank → 4 days

 x = 4 * (3/4) / 5 = 3/5 of a tank

 In 4 days you use 3/5 of a tank.

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

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
