What number should replace the question mark in the dessert equation?
Correct answer: 47
Explanation:
Let the cupcake be C, the ice cream cone be I, and the donut be D.
From the first equation:
C + C + C = 21
So C = 7.
From the second equation:
C + I + I = 19
Since C = 7, we get:
7 + I + I = 19
So 2I = 12, and I = 6.
From the third equation:
I + D + D = 16
Since I = 6, we get:
6 + D + D = 16
So 2D = 10, and D = 5.
The final equation is:
D + C × I
Using order of operations, multiply first:
5 + 7 × 6 = 5 + 42 = 47
Therefore, the missing number is 47.
