Let Vincent’s salary in November be x
November savings is 30%x =0.3x
Vincent’s salary in December is 40% less than x = 0.6x
December savings = 0.3 (0.6x) = 0.18x
given difference in saving = 138
138 = 0.3x - 0.18x
138 = 0.12x
x = $1,150
November savings is 30%x =0.3x
Vincent’s salary in December is 40% less than x = 0.6x
December savings = 0.3 (0.6x) = 0.18x
given difference in saving = 138
138 = 0.3x - 0.18x
138 = 0.12x
x = $1,150
