Answer:
32
Step-by-step explanation:
witch plus witch plus witch = 45 ⇒ witch = 45/3 = 15
broom plus broom plus a broom = 21 ⇒ broom = 21/3 = 7
spoon plus spoon plus spoon = 12 ⇒ spoon = 12/3 = 4
__
If we assume each witch on first line refers to a "loaded" witch that includes a broom and a spoon, then a "plain" witch is ...
plain witch = witch - broom - spoon = 15 -7 -4 = 4
and the final total of interest is ...
plain witch plus broom x spoon = 4 + 7 × 4 = 4 +28 = 32
