Final answer:
No, the relationship between Nobel's pay and Isaac's pay rate is not proportional.
Step-by-step explanation:
No, the relationship between Nobel's pay and Isaac's pay rate is not proportional. In a proportional relationship, the ratio between the two values remains constant. Let's create a table to compare their pay rates after each year:
Years Nobel's Pay Rate Isaac's Pay Rate
0 $12 $5
1 $15 $8
2 $18 $11
As shown in the table, each year Nobel's pay rate increases by $3, while Isaac's pay rate also increases by $3. However, the ratio between their pay rates is not constant, so the relationship is not proportional.
