40 x 8 is 320, and there’s 31,536,000 seconds in a year so multiply both of those :)
Answer: 56
Step-by-step explanation:
If the question is, "What is the scale factor." That would be a scale (factor) of 2.
I=PRT
I=interst
P=invested amount
R=rate in decimal
T=time in years
given
P=680
R=3.5%=0.035
T=6
I=680*0.035*6
I=142.8
that is interest
total is interest+principal=680+142.8=822.8
after 6 years, $822.80 is in the account
