A = $226.80
B = $201.50
C = $200
To find the tots with a markup, times the original amount by the percentage as a decimal (30% would be 0.30). Then add that amount back on.
The answer would be C because it is the cheapest.
B.
66%. Again, because it is the cheapest, if you offer more than the markup of both A and C- A will have to be cheaper. Thus, at least a 66% discount is the answer.
Hope that helps!
