Final answer:
The number 11 in Paul's earnings equation m = 12.5h+11 represents his fixed income or base pay before accounting for the hourly rate multiplied by the number of hours worked.
Step-by-step explanation:
The number 11 in the equation m = 12.5h + 11 where m represents the amount of money Paul earns and h is the number of hours he works, interprets as the initial amount of money or fixed income that Paul earns regardless of the hours he works. This could be a base pay or a standard fee that he receives.
The rest of the equation, 12.5h, indicates that for every hour Paul works, he earns an additional $12.50.
