What is the rate of inflation if an account has a nominal interest rate of 4.2% and a real interest rate of 2.8% A. 1%
B. 1.8%
C. 2.4%
D. 1.4%

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)
