Answer:
Mr. Johnson should be paid $285 for a job requiring 60 hours of work.
Explanation:
If Mr. Johnson was paid $190 for 40 hours of work, then we can write:
190/40 = x/60
Where x is the amount he should be paid for 60 hours of work.
To solve for x, we can cross-multiply and simplify:
190 * 60 = 40 * x
11,400 = 40x
x = 11,400/40
x = 285
Therefore, Mr. Johnson should be paid $285 for a job requiring 60 hours of work at the same rate.
