Usually if it's an basic good, or very important one.
because the price fluctuations do not affect the quantity sold.
a good example of that would be milk, if the milk gallon is say $8, and a family needs 1 gallon daily, they buy it for $8.
if the price drops to $7, they might buy 2, but they only need 1 everyday, just in case they may get another.
if the price drops to $4 or even $3, they're not going to get 10 gallons, there's no need for it on an everyday basis, besides is a perishable.
now if the price goes up to $12, they still need it, and will buy it for $12.
Answer:
Decrease by 13%
Step-by-step explanation:
You will take 140 times 5 since that is the amount she made so you times it buy the price she earns then after you do that subtract it buy 650 since that is what you have to pay
140 x 5 = 700
700 - 650 = 50
so she made a profit of 50
5
First you can add the two functions together, since that is what (h+k) is asking us to do.
x^2 + 1 + x - 2 ---> then simplify like terms
x^2 + x -1 ----> then plug in 2 for all of the x's in the equation
2^2 + 2 - 1 ----> and solve
4 + 2 - 1 = 5
