Question

FitURite garage employs one manager and four fitters. The average (mean) salary for all employees is £18600. If the manager's salary is £25000, what is the average salary of the fitters?

Answer 1

(25,000+4x)/5=18,600
25,000+4x=93,000 (multiply both sides by 5)
4x=68,000 (subtract 25,000 from both sides)
x=17,000 (divide both sides by 4)
Fitters make $17,000 a year
