I think I get it. They want it to have a markup that is 20% of the retail price instead of 20% of cost. We don't know the retail so we have to figure it backwards. We have to deduct 20% from retail: x(retail price) - .20x = 30.00. In other words, "the retail price minus 20% = $30". Okay, that makes sense.
An easier way to figure it out on multiple choice would be to take 20% away from the answer choices and see which one becomes $30.
Thanks Blue!
