Answer:
The percentage decrease is 7%
Step-by-step explanation:
To find the percent decrease, first find the difference in the two costs.
$210,000 - $195,300 = $14,700
Now divide that number by the original cost.
$14,700/$210,000 = 7%

Answer:
3m − 5
Step-by-step explanation:
(a - b)⁴ = a⁴ - 4a³b + 6a²b² - 4ab³ + b⁴
(a + b)⁴ = a⁴ + 4a³b + 6a²b² + 4ab³ + b⁴
Then
(a - b)⁴ - (a + b)⁴ = - 8a³b - 8ab³
… = -8ab (a² + b²)
… = -8 (∛100 - ∛10 + 1) (1 + ∛10)
… = -8 (∛100 + ∛1000 - ∛10 - ∛100 + 1 + ∛10)
… = -8 (∛1000 + 1)
… = -8 (10 + 1)
… = -8 • 11
… = -88
