13. We can solve this question as a VIC (Variable in answer choices)
by plugging in values for x, y and z:
x percent mark-up (1st)
10
y percent discount (2nd)
20
z original price
100
If a $100 item is marked up 10% the price becomes $110. If that
same item is then reduced by 20% the new price is $88.
If we plug x = 10, y = 20, z = 100 into the answer choices, only
answer choice (A) gives us 88:
