Final answer:
By comparing the salaries at different hours of training, it was found that the salary increases by $150 for every 10 additional hours of training, which means every hour of training raises the monthly salary by $15.
Step-by-step explanation:
To determine how much each hour of training raises the salary, we need to analyze the relationship between the hours of training and the corresponding monthly salary provided in the question. We can calculate the increase in salary per hour of training by taking the difference in salary for an increase in the number of training hours.
Looking at the salary data provided:
- At 10 hours of training, the salary is $1250.
- At 20 hours of training, the salary is $1400.
When the training increases by 10 hours (from 10 to 20 hours), the salary increases by $150 (from $1250 to $1400).
We can then divide the increase in salary by the increase in training hours:
$150 ÷ 10 hours = $15 per hour
Therefore, every hour of training raises the salary by $15.
