Money earned is directly proportional to the number of hours worked. M=k×H where M is the money earned, H is the number of hours, and k is the proportionality constant. Calculation: First, find the proportionality constant k : k=M∕H ⇒k=324∕6 ⇒k=54 Now, calculate the money earned for 29 hours of work: M=k×H ⇒M=54×29 ⇒M=1,566
