Solly is buying a camera and some rolls of film. The camera costs $163.00, and each roll of film costs $2.74. Tax is already included in the price of both the camera and the film. Which of the following equations can be used to determine the total price Solly is paying for his camera and film?

(Let x represent the number of rolls of film and y represent the total cost.)
y = $2.74x
y = $163.00x + $2.74
y = $2.74x + $163.00
y = x + 2.74
