Given that total revenue = price x quantity, what will happen to total revenue if price increases when demand is elastic?

the total revenue decreases

Step-by-step explanation:

In an elastic demand, an increase in price of of a product will lead to a large decrease in the quantity demanded resulting in a decrease in the total revenue acquired.

In the case above, given that the demand is elastic an increase in the price will lead to a decrease in the total revenue.

parallel and congruent

step-by-step explanation:

the movement of translation is linear.   these have the same translation because you are using the same rule for each point of the triangle so you will see the same slope being used to get from a point on the triangle to its image.

same slope!   you should think parallel when you see those 2 word together (well unless it's the same line but it can't be because we are coming from different points here)

congruent! because each point is being moved the same distance.

using pemdas, (order of operations) you'll see the answer is 24.
