Answer:
64.7%
Step-by-step explanation:
To solve this problem we use compounded interest formula.

a = amount
p = principle
r = interest rate
n = number of times compounded in a period
t = time period

a = 1647.01
1647.01-1000 = 647.01
647.01/1000 = 0.64701
0.64701*100% = 64.7%
The y intercept is the initial value, which is graphed on the y axis (or vertical line). In a word problem the y intercept is the original or starting value. In a graph you can find it where the data begins on the vertical axis.
