Use the following graph to answer the question below. The horizontal axis ranges from Q1 through Q4 and the vertical axis ranges from P1 through P4. A decreasing line is labeled demand. The data points at the demand curve (Q1, P4), (Q2, P3), (Q3, P2), and (Q4, P1) connects to both the axes with dotted lines, forming 10 squares. From left to right and top to bottom, the squares are labeled A, B, C, and D; E, F and G; H and I; and J.If the price increases from P1 to P2, then the total revenue will gain areasMultiple ChoiceA + B + C, but it will lose areas G + I + J.E + F + G, but it will lose area J.C + F + H, but it will lose area J.B + E, but it will lose areas H + I + J.

The question is asking about the change in total revenue when the price increases from P1 to P2 on a demand curve. Total revenue is calculated as the price per unit times the quantity of units sold.

When the price increases from P1 to P2, the quantity demanded decreases from Q4 to Q3 according to the demand curve. This means that the total revenue will gain the areas under the demand curve from P1 to P2, but lose the areas from Q4 to Q3.

Looking at the options, the correct answer is: "C + F + H, but it will lose area J."

Here's why:

• The total revenue gains areas C, F, and H. These are the areas under the demand curve from P1 to P2.
• The total revenue loses area J. This is the area under the demand curve from Q4 to Q3.

So, when the price increases from P1 to P2, the total revenue will gain areas C + F + H, but it will lose area J.
