Both a demand curve and a demand schedule show how

prices affect consumer demand.
consumer demand affects income.
prices affect complementary goods.
consumer demand affects substitute goods.

I believe the answer is: prices affect consumer demand.

Each consumers in the market have different level of income. As the price of a product increased, there would be less consumers that able to afford the product, which will lead to a decrease in the demand (the opposite thing happen if the price of the product decreased).

the perimeter of a triangle is 69 cm. side a is 5 cm shorter than side b. side c is twice as long as side a. find the length of each side. i need to know how to do it in 2 equations.  

equations:

a = b-5

c = 2a

a + b + c = 69

the correct answer is option d

the economy will face inflation
