Shane is thinking about apprenticing as a plumber and notes that master plumbers in his region of the country make about $55,000 a year starting out. However, salaries are expected to increase by about 10 percent over the next four years. How much can Shane expect to make when his apprenticeship is over in four years?

The amount Shane expects to make when his apprenticeship is over in four years is $60,500 a year

Step-by-step explanation:

The given information are;

The duration of Shane's apprenticeship = 4 years

The amount a master plumber makes = $55,000 a year

The expected salary increase in the next four years = 10%

Given that Shane can only be a master plumber after he completes his apprenticeship which is after four years, we have;

The amount Shane expects to make = 10% more than the current $55,000 a year

∴ Given that the current $55,000 can be represented as 100%, we have;

The amount Shane expects to make = 110/100 × $55,000 = $60,500 a year

The amount Shane expects to make when his apprenticeship is over in four years = $60,500 a year.
