Answer: 22
Step-by-step explanation
I'll use the letters g, h, and t where
- g = grinch
- h = hat
- t = tree
The first row represents g+g+g = 33.
g+g+g = 33 leads to 3g = 33 and solves to g = 11. Each grinch represents the number 11.
The third line translates to 25 = t + 7 + t. The steps to solving are shown below.
25 = t + 7 + t
25 = 2t + 7
2t + 7 = 25
2t = 25-7
2t = 18
t = 18/2
t = 9
Each tree represents the number 9.
Now turn to the second row. It translates to h+t = g
So,
h+t = g
h+9 = 11
h = 11-9
h = 2
Each hat represents the number 2.
Now we can figure out the last line
g + h + t = 11+2+9 = 22
The last line is: grinch + hat + tree = 22
