The cost of living last year went up ​%5. ​Fortunately, Alice Swanson got a ​%5 raise in her salary from last year. This year she is earning ​$23260. How much did she make last​ year?

Answer 1

Alice Swanson made $22,152.38 last year.

Explanation:

Alice Swanson’s salary last year can be calculated using the following formula:

salary_last_year = salary_this_year / (1 + raise_percentage)

where salary_this_year is Alice Swanson’s current salary, and raise_percentage is the percentage of raise she received from last year.

According to the problem statement, Alice Swanson’s current salary is $23,260 and she received a 5% raise from last year. Therefore, her salary last year can be calculated as follows:

salary_last_year = 23260 / (1 + 0.05) = $22,152.38

Therefore, Alice Swanson made $22,152.38 last year.
