Answer:
In math, ... means that a pattern will continue.
Step-by-step explanation:
For example -- you have 1,3,5,7,9... The ... will explain that the pattern will continue.
Simple interest: i = p * r * t; compound interest would be A=p(1+r/n)^(nt)
Here, A = $500 (1.10)^2 = $605 (answer for "once per year."
Once per month:
A = $500 (1 + 0.10/12)^(12*2) = $610.20
Once per week: Can y ou figure that out? # of compounding periods is 12 per year in this problem.
