Karla,
We can use a system of equations to solve this.
First, let 'x' represent the number of full-time employees and 'y' represent the number of half-time employees.
Then, we know a couple things.
(1) y = 1/2x (the number of half-time employees is equal to 1/2 the number of full-time employees.
We also know that:
(2) $35,000x + $17,500y = $1,225,000 (total salary in the budget is equal to the sum of the full-time and half-time salaries)
Now, substitute the value for y (1/2x) in eq1 for 'y' in eq2:
$35,000x + $17,500(1/2x) = $1,225,000
$35,000x + $8,750x = $1,225,000
$43,750x = $1,225,000
$43,750x/$43,750 = $1,225,000/$43,750
x = 28 full-time employees
To find the number of half-time employees, remember that:
y = 1/2x => y = 1/2 * 28 => y = 14 half-time employees.
Hope this helps.
