Answer:$90
Step-by-step explanation: $30 is the cost. 200 is the percent of Mark-up, so you take 100 percent of 30 and add it together then you get 60. Repeat that step for a total of 90. 100 percent of 30 is 30. So 30+ 30+ 30 = 90.
So we need to solve:
First is important to note that both terms on the left side of the equation have a common factor because they are both divided by y. Then:
Then:
So the solution is y=6. Then option A is correct and you need to write the 6 between the symbols { }.
Helen subtracted 17 from the right side of the equation when she should have added 17. Adding 17 to both sides would have gotten x/y by itself.
The answer is 'Helen should have added 17 to both sides of the equation'.
