Final answer:

The value of c is 10.21, which represents the change Pablo received after he paid his 9.79 lunch bill with a 20 bill.

Step-by-step explanation:

To find the value of c, we solve the equation given by Pablo's bar model, which details a transaction for lunch. The equation reflects the calculation made when Pablo pays with a 20 bill for a lunch that costs 9.79. To find the value of c, we start with the total amount Pablo paid and subtract the cost of lunch:

20.00 = c + 9.79

By subtracting 9.79 from both sides of the equation, we find the value of c:

20.00 - 9.79 = c
10.21 = c

Therefore, the value of c is 10.21. It represents the change Pablo received after paying for his lunch.
