Answer:
To calculate the total amount Tyler will have paid to the bank, you can use the formula for simple interest:
I = Prt
Where:
I = Interest (the amount Tyler will pay to the bank)
P = Principal (the original amount borrowed)
r = Interest rate (expressed as a decimal)
t = Time (in years)
Plugging in the given values, we have:
I = 42,000 * 0.05 * 15
I = 42,000 * 0.75
I = 31,500
So, Tyler will have paid a total of $31,500 in interest to the bank once he paid the loan back in full after 15 years.
