We assume the monetary amount is a number such that the hundredths place represents a penny. (It's not billions of dollars, for example.)

_____
Any calculator can give you the product. Most will round the number for you if you specify a 2 decimal digit display.
The thousandths digit of the product (8) is more than 4, so the hundredths digit (2) is increased by 1 (to 3) as the digits to its right are dropped.
2.4% = 2.4/100 or as a decimal fraction 0.024.
First order the numbers from least to greatest.
8,12,31, 45, 45,47, 48, 51,55
Min: 8
Q1: 21.5
Q2: 45
Q3: 49.5
Max: 55
To find Q1 find the average of the lower half. (12 + 31)/2
43/2 = 21.5
To find Q3 find the average of the upper half.
(48+51)/2= 49.5
Answer:
∠DAB = ∠DBA
Then AD=DB from above statement
