Answer» I-income, E-expenses and Savings-S Let, `I_a=5x and i_b=4x` `E_a=19y and E_b=21y` `S_a=37z and S_b=18z` Annual total savings=66000,monthly total savings=5500 `5500=37z+18z; z=100` `5x-19y=3700 and 4x-21y=1800` Solving these two equations by the method of substitution we get `x=1500`, monthly income of `A= 5x=1500=7500` |
