Answer:
20%
Step-by-step explanation:
Step 1: Subtract starting value minus the final value (decrease)
Step 2: Divide the decrease by the original number
Step 3: Multiply the result by 100 to get a percent decrease
Therefore, the percent decrease of the price of paper per package is 20%
<em>Note: If the percentage is negative, it means there was an increase and not a decrease.</em>
Answer:
Step-by-step explanation:
Area of triangle = 0.5 × Base × Height
→ Substitute in the values
200 = 0.5 × 5x × 5x
→ Simplify
200 = 12.5x²
→ Divide both sides by 12.5
16 = x²
→ Square root both sides
4 = x ∴ x = 4
