Ashopper paid $100 for a coat that was on sale for 20%. how much was the original price of the coat?

$125

When you are paying $100, you are paying 80% of the full price

Therefore you do 100/80=1.25

1.25*100=125

so what is the question

step-by-step explanation:

3< x< 5

step-by-step explanation:

|x - 4| < 1

there are two solutions, one positive and one negative.   remember to flip the inequality when taking the negative solution

x-4 < 1       x-4 > -1

add 4 to each side

x-4+4 < 1+4       x-4+4 > -1+4

x< 5                 x> 3

3< x< 5
