Mr. Wilk's salary for 180 days = $33,660

Mr. Wilk's salary for 1 day = $?

By unitary method:

Days Salary

180 $33,660

1?

By cross-multiplication:

1*33660/180

33660/180 = $187

Mr. Wilk's salary per day = $187

Substitute teacher's salary per day = $85

Difference in salary = 187-85

= $102

The school district pays $102 less to the substitute teacher.
