Question

chang made $171 for 9 hours of work. at the same rate, how much would he make for 5 hours of work?

Explanation:

Step1: Find the hourly rate

To find the hourly rate, we divide the total money earned by the number of hours worked. So, the hourly rate \( r \) is \( r=\frac{171}{9} \). Calculating this, \( \frac{171}{9} = 19 \) dollars per hour.

Step2: Calculate money for 5 hours

Now, to find out how much Chang makes for 5 hours, we multiply the hourly rate by 5. So, the money earned \( M = 19\times5 \). Calculating this, \( 19\times5=95 \).

Answer:

\( 95 \)
