Final answer:
To calculate the number of deposits needed for an RRSP to reach $42,674 with a 4.14% compounded interest, we must align the deposit and compounding frequencies. Without the ability to adjust for the quarterly deposits and semi-annual compounding, an exact answer cannot be provided. Additional information is needed to solve this problem accurately.
Step-by-step explanation:
Calculating how many deposits Peter will need to make to accumulate $42,674 in an RRSP with a 4.14% interest rate compounded semi-annually involves using the future value formula for an annuity. However, since the interest is compounded semi-annually and the deposits are quarterly, we must adjust the compounding period or the deposit period so that they align.
Unfortunately, without additional information or a clear formula to align the different deposit and compounding frequencies, we cannot provide an exact answer. Typically, the formula for the future value of an annuity does not directly account for different deposit and compounding frequencies without adjustment.
We recommend reviewing the problem to ensure all necessary details are provided and seeking additional information on how to handle the mismatched deposit and compounding frequencies.
