Question 2
A)
Jairo works for his uncle's lawn care company after school, on weekends, and on school holidays. The table below shows the number of hours that Jairo has worked and the amount of money that Jairo earned for his last five work days.
Two values are missing. Jairo is always paid the same hourly rate.
Fill in the two missing values in the table.
(1 point)
Number of Hours Worked 2 4 7 _ 12
Amount of Money Earned $32 $64 _ $176 $192
Number of Hours Worked - 2, 4, 7, 10, 12
Amount of Money Earned - $32, $64, $112, $176, $192
How do you know
To find the missing values in the table, we can calculate the hourly rate that Jairo is paid. We can do this by finding the amount earned per hour for the known values.
First, we calculate the amount earned per hour for the known values:
- For 2 hours of work, Jairo earned $32. So, the amount earned per hour is $32 / 2 hours = $16 per hour.
- For 4 hours of work, Jairo earned $64. So, the amount earned per hour is $64 / 4 hours = $16 per hour.
- For 7 hours of work, we need to find the amount earned. Using the hourly rate of $16 per hour, we can calculate 7 hours * $16 = $112.
- For 12 hours of work, Jairo earned $192. So, the amount earned per hour is $192 / 12 hours = $16 per hour.
Therefore, the missing values are:
- For 7 hours of work, the amount earned is $112.
- For 10 hours of work, the amount earned can be calculated as 10 hours * $16 per hour = $160.
