Francis heard that a car stereo system was on sale for 30% off. If the sale price was 57.75, what was the original price of the stereo?

Step-by-step explanation:

First, what I do is I multiply the 57.75 by 0.30 which would get me 17.325 and then add it to the sale price, which adds up to a total of 75.075. Round that to the nearest hundrednth, and you got your answer!

Hope this help you!

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
