(a) Explanation Formula used: “The percent of proportion can be calculated as part base = rate 100 .” Calculation: Given that for engineering technicians, the life time earning of a high school diploma is $1,900,000 and the life time earning of a college graduates is $2,200,000. The difference in earning is $ 2 , 200 , 000 − $ 1 , 900 , 000 = $ 300 , 000 . Find the percent increase in lifetime earnings as follows. 300 , 000 1 , 900 , 000 = x 100 x = 300 , 000 × 100 1 , 900 , 000 x = 16 Given that for computer scientists, the life time earning of a high school diploma is $2,200,000 and the life time earning of a college graduates is $3,000,000. The difference in earning is $ 3 , 000 , 000 − $ 2 , 200 , 000 = $ 800 , 000 . Find the percent increase in lifetime earnings as follows. 800 , 000 2 , 200 , 000 = x 100 x = 800 , 000 × 100 2 , 200 , 000 x = 36 Given that for fire fighters, the life time earning of a high school diploma is $2,100,000 and the life time earning of a college graduates is $2,700,000. The difference in earning is $ 2 , 700 , 000 − $ 2 , 100 , 000 = $ 600 , 000 . Find the percent increase in lifetime earnings as follows (b) To determine The occupation which showed largest percent increase for a college degree. (c) To determine The occupation which showed smallest percent increase for a college degree.
