Step-by-step Solution
Substitute \( x=2025-2017 \) into the expression \( -3.72x+152.46 \).
Evaluate the expression by following steps:
- step0: Evaluate:
\(-3.72x+152.46\)
- step1: Substitute:
\(-3.72\left(2025-2017\right)+152.46\)
- step2: Subtract the numbers:
\(-3.72\times 8+152.46\)
- step3: Multiply the numbers:
\(-29.76+152.46\)
- step4: Add the numbers:
\(122.7\)
The predicted diamond production in 2025 is $122.7 billion.
Quick Answer
Predicted diamond production in 2025: $122.7 billion.
