Answer:
A. Total Money Contributed after n months = 
B. Total Money Contributed after 24 months = 
Step-by-step explanation:
Given:
Initial contribution = 
each month contribution =
After 1 month contributed = 
Solving for Part A
let n be the number of months
∴ Total Contribution after n months = Initial contribution + (each month contribution
Number of months = 
Solving for Part A
Now n= 24 months
∴ Total Contribution after 24 months = 
20% = 20/100 = 1/5
1/5 of 3500
1/5 X 3500/1 = 3500/5
3500/5 = 700.
This statement is false because a whole number is a number that is a positive number that doesn't have a fraction or decimal.
