Answer:
The senior class will have 100 members in the 13th year.
Step-by-step explanation:
Use the compound interest equation with a negative interest rate:
A = P(1 + r/n)^(n)(t)
Let n be 1 since we're looking for a specific year.
100 = 250(1 - 0.07)^t
100/250 = (0.93)^t
0.4 = (0.93)^t
t = 13 years
The answer would be A.
Here's steps:
The original equation would be 9 x 17
But there are 3 more in each box which would create
9 x 20
When you solve that, it becomes 180.
