b
621=83(7)+b; b= $1
c
621=83(7)+b; b= $40

Answer:

Correct option is c.

Step-by-step explanation:

The information provided is:

  • It costs $83 a day to rent a car plus a required fee for insurance.
  • The total cost for renting the car for 7 days is $621.

Then the cost of renting the car for 7 days will be, (83 × 7).

Let b denote the required fee for insurance.

Then the equation representing the total cost of renting is:

621 = 83(7) + b

Compute the value of b as follows:

621 = 83(7) + b

621 = 581 + b

b = 40

So, the correct option is c.
