We can write b= boys, and g= girls
we know that girls are equal g=(2*b-5)
we also know that b+g=40
we will replace girls with the above equation and get
b+ (2*b-5) = 40 , 2*b=2b
b+2b= 40+5
3b=45, divide everything by 5
b=15
girls are 2*15-5=25
15+25=40
This is a geometric sequence:
First month: 8
Second month: 8 * 1.02
Third month: 8*1.02^2
Fourth month 8* 1.02^3
...
nth month: 8 * 1.02 ^(n-1)
Sum of the first 9 terms (months) = a[1 -r^n] / (1 - r) = 8* [1 - 1.02^9] / (1 - 1.02) = 78.04
