If the cost of the shirt is increased 30%, then the new price of the shirt is 130% of the original price. If the original price was k, then the new price is 1.3k.
Remember that it is this new price that is increased by 50%. Multiply 1.3k by 1.5 (150%) to get the final price of the shirt: 1.3k × 1.5 = 1.95k
Answer: E.

30% increase means multiply the existing price by (1 + 30/100) = 1.30. Likewise, in case of 50% increase, it will be (1 + 50/100) = 1.50
So, We can do this in a single line: New price = k * 1.30 * 1.50 = 1.95k (E)
So, We can do this in a single line: New price = k * 1.30 * 1.50 = 1.95k (E)
