Final answer:
Maggie will earn £18,300 at the end of 2022, calculated by adding the total pay raise of £2200 (4 years × £550 per year) to her 2018 salary of £16,100.
Step-by-step explanation:
The student has asked how much Maggie will earn at the end of 2022 if she earns £550 more each year and her salary at the end of 2018 was £16,100. To find the answer, we need to calculate the total pay raise over the given number of years and then add it to her salary in 2018.
From the end of 2018 to the end of 2022 is a total of 4 years. The annual pay rise is £550.
To calculate the total pay raise over 4 years, you simply multiply the annual pay rise by the number of years:
Total pay raise = annual pay rise × number of years = £550 × 4 = £2200.
Maggie's salary at the end of 2022 can be determined by adding this total pay raise to her salary at the end of 2018:
Salary at the end of 2022 = salary at the end of 2018 + total pay raise = £16,100 + £2200 = £18,300.
Therefore, Maggie will earn £18,300 at the end of 2022.
