Answer:
17
Step-by-step explanation:
60 students in total, that means girls are 40 in number and boys are 20 in number (because girls are twice the number of boys).
If girls are 40 in total
Boys are 20
With 9 boys ahead of melissa, that means ( we will use 26 because she is in 27th)
26-9 = 17
This means 17 girls are ahead of melissa.

Step-by-step explanation:
Formula for compound interest is
Interest = Amount - Principal
Interest = 
- P
Where r = rate in percent
t = time in years
For Jaina,
P = $300
r= 7%
t = 3 yrs
So, Interest = 
- 300
For Tomas
P = $400
r= 4%
t = 3 yrs
So, Interest = 
- 400
So pair of equations for Jaina and Tomas are
Interest = - 300
Interest = - 400
