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
Answer:
1200 Quarts of Water
Step-by-step explanation:
Starting off with 3600 gallons of water, we know that this needs to be changed to quarts, which to do this you multiply it by 4.
3600 x 4 = 14400
This now shows how many quarts of water are wasted every year, but we need it in months. To do this, we divide by twelve because there are 12 months in a year.
14400 / 12 = 1200
This leads you with the answer of 1200 quarts of water being wasted every month.
