Answer:
the answer for your question is 9 31/42
Answer:
Proportion states that the two fractions or ratios are equal
Given the equation: 
By cross multiply we get;
Using distributive property; 
Subtract 0.4 from both sides we get;
Subtract 1.5x from both sides we get;
Divide both sides by 0.1 we get;
Simplify:
x = 56
Therefore, the value of x that satisfy the equation is, 56
The only restraints on profit result from the restriction on the domain which in turn place a restriction on profit.
0≤k. Knives sold cannot be negative.
So the range of profit or p is:
p=[-500, +oo)
Profit increases as the number of knives sold increases. $200 more profit is gained by each sale of a knife.
4000=200k-500
4500=200k
k=22.5
Since k is for knives sold, it must be an integer value, so a $4000 profit is not possible. At 22, p=3900 and at 23, p=4100
1:2
Similar to the 1/2 fraction, 1:2 is a simplified ratio of a half.
