Two days ago, Oliver's shop washed a total of 5 kilos of laundry, so he earned 5 * $2 = $10.
Yesterday, his shop washed five kilos more than the previous day, so they washed 5 + 5 = 10 kilos of laundry.
So, Oliver earned 10 * $2 = $20 yesterday.
Today, his shop washed twice the number of kilos than yesterday, so they washed 10 * 2 = 20 kilos of laundry.
Therefore, Oliver earned 20 * $2 = $40 today.
In total, Oliver earned $10 + $20 + $40 = $70 for three days.
#### 70
