Same as the other one
part A)
CD 12,000 at 6%, how much is that? (6/100) * 12000
CB 4000 at 5%, how much is that? (5/100) * 4000
part B)
total investment was 12000 + 4000 = 16000
the earned interest above are 720 and 200 respectively
total yield was, 720 + 200 = 920
if 16000 is the 100%, how much is 920 in percentage?

solve for "x"

Answer:
1.95 x 10^5
Step-by-step explanation:
First look at the 4th digit in the number 194720 as the the question said to round to 3 significant figures. If the 4th digit is more than 5, then add 1 to the third digit which results in 195000. Now the question also said to express in standard form. Look for the first non-digit number in 195000. After 1 put a decimal point and remove all the zeros after the point which results in 1.95. Now count how many digits you moved to the left which comes as 5. Write the answer as 1.95 x 10^5.
Hope you can understand this!!
