David found a new part-time job that pays $2,400 a month. This is five times what he made at his previous job. What was David's yearly salary at his old job

1 answer

To find David's yearly salary at his old job, we need to divide his monthly salary at his new job by the number of times he was earning at his old job.

Yearly salary at old job = Monthly salary at new job / Number of times he was earning at old job

Number of times he was earning at old job = 5

Monthly salary at new job = $2,400

Yearly salary at old job = $2,400 / 5 = $<<2400/5=480>>480

Therefore, David's yearly salary at his old job was $480.
