kyle just started a new job that pays $7 per hour. He had been making $5 per hour at his old job. Kyle worked a total of 54 hours last month and made $388 before deductions. How many hours did he work at his new job?

56 hours

To figure out how many hours Kyle worked at his new job, we need to know the hourly rate difference between his old and new jobs.

The hourly rate difference is calculated by subtracting the hourly rate of his previous job from the hourly rate of his new job:

Hourly rate difference = New job hourly rate - Old job hourly rate

In this case, the hourly rate difference would be:

Hourly rate difference = $7 - $5 = $2

Now, let's figure out how many hours Kyle worked at his new job.

We know that Kyle made a total of $388 last month and the total number of hours worked is 54. To find out how many hours he worked at his new job, we need to determine how much he earned at his old job first.

To calculate his earnings at his old job, we will multiply the difference in hourly rates by the number of hours worked:

Earnings at old job = Hourly rate difference × Number of hours worked
Earnings at old job = $2 × 54 = $108

Now, we can find out how many hours Kyle worked at his new job by subtracting his earnings at his old job from his total earnings:

Earnings at new job = Total earnings - Earnings at old job
$388 - $108 = $280

Since Kyle's new job pays $7 per hour, we can calculate the number of hours he worked at his new job by dividing his earnings at his new job by the hourly rate:

Number of hours worked at new job = Earnings at new job / Hourly rate
Number of hours worked at new job = $280 / $7 = 40 hours

Therefore, Kyle worked 40 hours at his new job.
