Hey there I just saw no one answered this problem and I know this is a little late but I will answer it anyways.
Answer: The answer to this problem would be points A and B
Answer:
MRS is the demand side of equation while MRT is for the supply side.
MRS defines how much a consumer is willing to give up of good X for 1 additional unit of good Y to stay on the same utility level. It is shown by indifference curve. MRS = Price of X/ Price of Y
Similarly, MRT is how much a supplier is willing to give up producing good X for 1 additional unit of good Y. It is shown by Production Possibility Frontier. MRT = MC of X/ MC of Y
The equation has one solution, x = -7.
To find the percent of change, subtract to find the amount of change
387 - 207 = 180. The increase is 207.
Then divide the amount of change by the original amount
207 ÷ 180 = 1.15
Change the decimal to a percent, and multiply the number by 100:
1.15 X 100 = 115
The answer is 115%
