9 and 10

Important:

1. Don't include signs like $ or % in your answers.
2. Pay close attention to the rounding instructions. For example, if the question instructs you to "round to the nearest cent" or "round to two decimal places", and the answer you found is $12,678.04678, you need to submit 12678.05. Some questions may ask you to round to the nearest whole number or nearest dollar, in which case the answer would be 12678.

Tolerance: Be careful with rounding and do not round until you arrive at the final answer. Answer tolerance is 1 at the last digit based on the decimal place accuracy required by that question. For example, if a question asks you to round to the nearest cent (two decimal places) and the correct is $1,235.06, answers within 0.01 ($1,235.05 to $1,235.07) will count as correct. As another example, if a question asks you to round a percent answer to one decimal place and the correct answer is 4.6%, answers within 0.1% (4.5% to 4.7%) will count as correct.

An investment is expected to earn you $3,000 each quarter for the next 15 years. If the appropriate discount rate is 7%, how much is this investment worth today? Round to the nearest dollar.

If you deposit $8,000 each year for the next 17 years into an account paying 2.1%, how much in interest will you earn over that time period? Answer in dollars rounded to a whole number.
