The figure displays a closed cycle for a gas. From c to b, 50 J is transferred from the gas as heat. From b to a, 130 J is transferred from the gas as heat, and the magnitude of the work done by the gas is 80 J. From a to c, 400 J is transferred to the gas as heat. What is the work done by the gas from a to c? (Hint: You need to supply the plus and minus signs for the given data.)
