To find the average age of the entire group, we need to calculate the total combined age of all individuals and then divide by the total number of individuals. Total combined age of males = 30 males * 70 years = 2100 years Total combined age of females = 20 females * 40 years = 800 years Total combined age of the entire group = 2100 + 800 = 2900 years Total number of individuals = 30 males + 20 females = 50 individuals Average age of the group = 2900 years / 50 individuals = 58 years
On average, between $30 to $40.
