Calculate her pay every year then add:
Year 1: 21, 500
Year 2: 21,500 x 1.03 = 22,145
Year 3: 22,145 x 1.03 = 22,809.35
Year 4: 22809.35 x 1.03 = 23,493.63
Year 5: 23493.63 x 1.03 = 24,198.44
Year 6: 24198.44 x 1.03 = 24,924.39
Year 7: 24,924.39 x 1.03 = 25,672.12
Total made: 21, 500 + 22,145 + 22,809.35 + 23,493.63 + 24,198.44 + 24,924.39 + 25,672.12 = 164,742.93
