Proportionality of what Jacob earns 5 hours $37.50 8 hours $60 11 hours $85.50 16 hours 14120
To determine the proportionality of what Jacob earns, we can divide the earnings by the number of hours worked and see if the ratio remains constant.
For 5 hours: $37.50/5 = $7.50 per hour
For 8 hours: $60/8 = $7.50 per hour
For 11 hours: $85.50/11 = $7.77 per hour (rounded)
For 16 hours: $141.20/16 = $8.82 per hour (rounded)
As we can see, the ratio does not remain constant. Therefore, we can conclude that Jacob's earnings are not proportional to the number of hours worked.
