Mary sold shoes for $200. Mary increases her sales price by 100%. What is the sales price of a pair of shoes? (Show the work, if you do I will give brainlist!)

if 100% of something is the whole thing and she increased it by 100% that means the price she sold the shoes is 200%. 200÷2 100. original price was $100

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
