Final answer:
The train engineer will earn a lifetime income of $1,670,130, while the crane operator will earn $1,644,900. The train engineer will make $25,230 more over their working career than the crane operator.
Step-by-step explanation:
The question is about calculating the lifetime income of two professionals based on their annual salaries and the number of years they work. To find out who makes the most lifetime income, we can multiply the annual salary of each profession by the number of years each professional works. For the crane operator, the annual salary is $54,830 and they will work for 30 years. For the train engineer, the annual salary is $50,610 and they will work for 33 years.
Crane Operator's Lifetime Income:
$54,830 × 30 years = $1,644,900
Train Engineer's Lifetime Income:
$50,610 × 33 years = $1,670,130
The train engineer makes more money over their lifetime. To determine how much more, we subtract the crane operator's lifetime income from the train engineer's lifetime income:
$1,670,130 - $1,644,900 = $25,230
Therefore, the train engineer will make $25,230 more over their working career than the crane operator.
