Answer:
A = 1000 ( 1 + .031/12) ^(12t)
The approximate monthly interest rate is .2583 percent
Step-by-step explanation:
A=1000(1.031)^t
The formula for compound interest is given by
A = P(1 + r/n) ^ (nt)
Take 1.031 and subtract 1
.031 is the yearly rate in decimal form
A = 1000 ( 1 + .031/12) ^(12t)
Change to a percent = 3.1 %
Divide by 12
3.1/12 = .2583333333(repeating) %
This would be the monthly rate

Answer:
B. 23 games.
Step-by-step explanation:
Current balance: $469
Goal balance: $825.50
Profit per game: $15.50
- 825.50 - 469 = 356.50
They only need $365.50 in order to reach the goal.
- 356.50 ÷ 15.50 = 23
They need to sell 23 games, each selling for $15.50, in order to reach their goal balance, of $825.50.
- Therefore, the answer is B.
