Answer:
A- The final price of the shirt was $27.36.
B- If it were reduced by 30% from the original price, the price of the shirt would be $26.6.
C- There is a difference between both prices because in the first case, the discount is split, making a first discount on a larger basis, and the second on a smaller basis, already made the first discount.
In contrast, at the second price, the entire percentage is made on the major basis. Therefore, the discount is larger.
Step-by-step explanation:
A- The final price of the shirt is determined by the following calculation:
(38 x 0.8) x 0.9 = FINAL PRICE
38 is multiplied by 0.8 because the price was reduced by 20% (0.2 is the 20% of 1, that is, of a unit. Therefore, the remaining price would be that 0.8 or 80%)
Then, using the same logic, we have to multiply that result by 0.9 in order to get the final price.
Therefore:
(38 x 0.8) x 0.9 = 30.4 x 0.9 = 27.36
B- Here, we would have to multiply 38 x 0.7, which gives a result of 26.6
