algebraDamon and Kisha have each set up three savings accounts: "Vacation Savings," "Student Loan Savings" and "Taxes Savings” Examine their savings budget matrices. Let D represent Damon's savings budget matrix and K represent Kisha's savings budget matrix. Damon's monthly vacation savings amounts can be determined by the arithmetic sequence whose formula is $D_{1, m}=80+15(m-1).$ His monthly student loan savings amounts can be determined by the geometric sequence whose formula is $D_{2, m}=200(1.1)^{m-1}.$ His tax savings amounts can be determined by the sequence $D_{3, m}=50.$ In each of these cases, $m=\{1,2,3,4,5\}.$ Kisha's monthly vacation savings amounts can be determined by the arithmetic sequence whose formula is $K_{1, m}=50+20(m-1).$ Her monthly student loan savings amounts can be determined by the geometric sequence whose formula is $K_{2, m}=100(1.2)^{m-1}.$ Her taxes savings amounts can be determined by the sequence $K_{3, m}=75.$ In each of these cases, $m=\{1,2,3,4,5\}.$

Damon has decided to decrease his vacation savings by 2%, his loan savings by 1%, and his taxes savings by 10%. He has created the following percent decrease matrix: =[0.98 0.99 0.90]. Determine matrix PD. What do the elements represent?
