The average yearly salary of a construction worker is $11 thousand less than three times that of a fast-food worker. Combined a fast-food worker and a construction worker earn $65 thousand. Find the average yearly salary of a fast-food worker and a construction worker.

Answer 1

Here is how to do the problem

x=construction worker salary

y=fast food worker salary

x+y=65

x+11=3y

Substitution.

x=65-y

65-y+11=3y

4y=76

y=19

x+19=65

x=46

const. worker salary = 46k

fast food = 19k
