Asalad dressing recipe requires at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice in a 16-ounce container. write an inequality to model the problem.

Given

A salad dressing recipe requires at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice in a 16-ounce container.

Find the inequality of this problem

To proof

As given

A salad dressing recipe requires at least  ounces of oil = 8 ounces

let us assume that the  at least 8 ounces of oil to be combined with some combination of vinegar  and lemon juice be x.

Total container capacity =  16-ounce

than the equation is

8 + x ≤ 16

x ≤ 8

i.e   some combination of vinegar  and lemon juice be 8 ounces.

when at least 8 ounces of oil to be combined with some combination of vinegar and lemon juice.

Hence proved

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
