Caroline's clothing store buys coats for $50 and then sells them for $80. what is the percent of mark up on the price of the coat? show how you did it

60

Step-by-step explanation:the percent markup will be 60

Because I subtract 80 by 50 it gave me 30 then I dived 30 by 50 which gave me 0.6 then I move two decimals place which is 60

x = -4

step-by-step explanation:

- 20 - 4(x + 3) = 4x

=> -20 - 4x - 12 = 4x

=> - 32 -4x = 4x

=> -32 = 4x + 4x

=> - 32 = 8x

=> -32/8 = x

=> -4 = x

explanation:

previous steps have made pa≅ pb ≅ st ≅ su. setting the compass width to ab allows you to make tu the same length. then δstu ≅ δpab by the sss congruence postulate, and ∠p ≅ ∠s by the reason cpctc.
