Step-by-step explanation:
It seems to be easiest to simply try the answers and see what adds up.
A) 2×12 +3×13 = 24 +39 ≠ 61
B) 2×11 + 3×14 = 22 +42 ≠ 61
C) 2×14 +3×11 = 28 +33 = 61 . . . correct answer choice
D) 2×10 +3×15 = 20 +45 ≠ 61

If you want to solve the equations, it can work well to let s represent the number of sugar sticks (the higher cost item). Then the revenue equation is ...
2(25 -s) +3s = 61
50 +s = 61
s = 11 . . . . . . . matches answer choice C
