I need to know the standards deviations and cost for the 3 stratas above knowing that the rural strata will have the highest std dev and cost. solve the equations.

We wish to estimate the amount of money spent on groceries per week in a certain very large city. The city's residents are classified into 3 strata: urban (50%), suburban (30%), and rural (20%). Furthermore, assume that the strata standard deviations satisfy: 1.500 = 1.20 s = 0 R. Finally, the cost of sampling a unit in a given strata satisfies: 3Cu = 1.569 = CR. Note: the rural area has the highest std dev and the highest cost. We wish to estimate the amount of money spent on groceries per week in a certain very large city.
