Answer: 2.5t
If Kyle practices 2.5 times as many hours as grant does, you have to multiply grants time by 2.5
Answer:
$15,339
Step-by-step explanation:
C(x) = 0.5x² − 100x + 20,339
Since this is a parabola, the minimum cost is at the vertex:
x = -b / (2a)
x = -(-100) / (2 × 0.5)
x = 100
So the minimum cost is:
C(100) = 0.5(100)² − 100(100) + 20,339
C(100) = 15,339
First distribute the -3 to 4x + 3
It'll be -12x - 9
Then distribute 4 to 6x+1
It'll be 24x+4
-12x - 9 + 24x + 4 = 41
Add the like terms
12 x -5 = 41
12 x = 46
x = 46/ 12
In fractions the answer is 23/6
In decimals the answer is 3.84
