Final answer:
To find Jack's new salary after a 10% increase on his original salary of $56,000, we can calculate the increase and add it to his original salary. The new salary is $61,600.
Step-by-step explanation:
To find Jack's new salary, we need to calculate a 10% increase on his original salary of $56,000.
First, we need to calculate the amount of the increase. We can do this by multiplying Jack's original salary by 10% (or 0.1).
$56,000 * 0.1 = $5,600
Then, we add the increase to Jack's original salary to find his new salary:
$56,000 + $5,600 = $61,600
Therefore, Jack's new salary is $61,600.
