Explanation:

Given: I = Prt ; Solve for "r" ;
______________________________________
Rearrange the equation; to isolate "r" on one side of the equation; then plug in our given values to solve for "r" ;
_________________________________________________
I = P r t ;
_________________________________________________
Divide EACH SIDE of the equation by "P*t" (that is: "(Pt)" ;
to get: "r" on one side of the equation ;
_________________________________________________
I / Pt = (Prt) / (Pt) ;
to get: I / Pt = r ;
↔ r = I / Pt ;
GIven: Interest = I = 3240 ;
Principal = P = 18000 ;
time (in "years") = t = 6 ;
_________________________________________________
Plug in our given values to solve for " r " ("rate") ;
_________________________________________________
r = I / (P t) ;
→ r = 3240 / (18000 * 6) ;
→ r = 3240 / (108000) ;
→ r = 3/100 = 0.03 = 3%

To set up an equation correctly, it is important to understand the problem statement and the given values. We do as follows:
initial number of balls = 14 + 23 = 37
number of baseballs per box = 12
number of tennis balls per box = 16
we let x as the number of boxes
Total number of balls = 37 + 12x + 16x
Total number of balls = 37 + 28x
yes 11.5 is bigger than 8.5 by 3
