His brother has already collected $80 and he plans to earn $40 weekly
Let's start off with Joe and the amount he will be earning weekly

Second week: 190 + 20 = 210
Third week: 210 + 20 = 230
Fourth week: 230 + 20= 250
Fifth week: 250+20= 270
Next is to calculate Joe's brother earnings
First week: 80 + 40 = 120
Second week: 120 + 40 = 160
Third week: 160 + 40 = 200
Fourth week: 200 + 40= 240
