When we move upward and to the left along a linear, downward-sloping demand curve, price elasticity of demand a. first becomes larger, then smaller. b. always becomes larger. c. always becomes smaller. d. first becomes smaller, then larger.

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
