What number should replace the question mark in the mushroom equation?
Correct answer: 59
Explanation:
Let the red mushroom be R, the brown mushroom be B, the pair of small beige mushrooms be P, and the purple mushroom be U.
From the first equation: R + R + R = 24, so R = 8.
From the second equation: R + B + B = 20. Since R = 8, we get 8 + B + B = 20, so B = 6.
From the third equation: B + P + P = 18. Since B = 6, we get 6 + P + P = 18, so P = 6.
The pair of small beige mushrooms is worth 6, so one small beige mushroom is worth 3.
From the fourth equation: P + U + U = 20. Since P = 6, we get 6 + U + U = 20, so U = 7.
The final equation is: single beige mushroom + red mushroom × purple mushroom.
Using order of operations, multiply first: 3 + 8 × 7 = 3 + 56 = 59.
