Final answer:
After John receives a 4% pay rise on his original salary of $238.50, he will earn $248.04 per week. The increase is calculated by multiplying his original salary by 4% and adding the result to the original salary.
Step-by-step explanation:
To determine John's new weekly earnings after a 4% pay rise, a straightforward calculation involves finding the increase amount and adding it to his original salary. John's original weekly earnings are $238.50, and the 4% pay rise can be calculated by multiplying this amount by 0.04 (4% as a decimal):
pay increase=$238.90*0.04=$9.54
This indicates that John's pay will increase by $9.54 per week. Adding this increase to his original salary gives the new weekly earnings:
new weekly earning=$238.50+$9.54=$248.04
Therefore, after a 4% pay rise, John's new weekly earnings will be $248.04.
This calculation is essential for both employees and employers to understand the financial impact of a pay raise. It ensures clarity regarding the adjusted compensation and allows individuals to plan and budget accordingly. For John, this increase not only reflects a positive change in his income but also acknowledges his contributions and potentially boosts morale and job satisfaction. Overall, transparent communication about salary adjustments is crucial in maintaining a positive employer-employee relationship and fostering a motivated workforce.
