Answer:
33
Step-by-step explanation:
each upper cell is the sum of the two cells under it. For example 4 and 5 make 9 so 16+17=33
The answer is A because 9x times 0 = 0 and 3y times -6 = -18
The price after the sale is (18/22.5)*100 = 80% from the original price
so, the percentage of decrease in the price of the shirt is 100% - 80% = 20%
another way,
how much is decreased / original price *100
(22.5-18) / 22.5 *100 = 20%
