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
Answer:
80
Step-by-step explanation:
we search for a square number so that rows*plantsInARow gives us the number
The number should be around 50², guessed
50² = 2500 (to low)
51² = 2601 (still to low)
52² = 2704 (bingo)
now to get from 2624 to 2704 plants he needs 80 more. That is the least number.
He could also go to plant 60² plants an than need slot more.
