There are 52 weeks in a year. Divide that by 2 and you get 26. That's 26 paychecks Toni will receive in a year. To find out how much he earned for each paycheck, you take 26 and divide it into the salary.
39,500/26=1,519.23.
Toni made 1,519.23 with his old salary
44,230/26=1701.15
Toni makes 1701.15 with his new salary.
Now you take the new paycheck and subtract it from the old paycheck.
1701.15-1,519.23=181.92.
Toni receives $181.92 more on each paycheck this year.
