Marla invested $78,170 in a simple interest account. After 9 years and no additional deposits or withdrawals, the account balance was $150,606.59. Find the interest rate for the account.

10% interest

Step-by-step explanation:

150,606.59 - 78,170 = 72,436.59

72,436.59 / 9 = 8,048.51

8,048.51 / 78,170 = 0.1029... = 10%

the mistake in the pattern is that :

b. the decimal point was moved one too many place values each time

the correct pattern could be made by :

b. moving the decimal point to the right the same numbers of place values as the exponents

a reflection across the x-axis , followed by the by a reflection across the y-axis , and then a scale dilation of 0.5 .
