Step-by-step explanation: 5/12
Answer:
x = 7
Step-by-step explanation:
Let x = the number. Then
"Triple a number" means 3x
"is the same as" means =
"double the number increased by 5" means 2x + 7
∴ 3x = 2x + 7
Subtract 2x from each side
x = 7
The answer is x = 7.
Check:
3 × 7 = 2 × 7 + 7
21 = 14 + 7
21 = 21
OK.

6/8 y=79

X = k/p^3
125 = k/10^3 = k/1000
1000 x 125 = k
k = 125000
x = 125000/p^3
The profit is given by G = px - (125 + 2x) = p(125000/p^3) - 125 - 2(125000/p^3) = 125000/p^2 - 250000/p^3 - 125
For maximum profit:
dG/dp = 0
dG/dp = -250000/p^3 + 750000/p^4 = 0
750000 - 250000p = 0
p = 750000/250000 = 3
Therefore the price that will yeaild maximum profit is $3.
