In 1939 a hamburger sold for 5 cents, but a worker would only earn 30 cents/h. If in a later year, a hamburger sells for 85 cents, how would the worker earn if earnings went up at the same rate?

Since a worker only earns 30 cents per hour which is 6x hamburgers back in 1939.
You can apply that rate to the hamburger in that later year which is 85x6= 510 cents or $5.10
