The table shows a proportional relationship between the number of cartons of eggs, X, and the cost of the cartons of eggs, Yin dollars , in Grayson City The cost of a carton of eggs in Branson City is twice as much as in Grayson City. Travis says that since a carton of eggs costs twice as much in Branson City, the equation expressing the relationship between the number of cartons of eggs, X and the cost of the cartons of eggs, y, in dollars, in Branson City is y = 2x . Which statement is correct?
A construction team gives an estimate of three months to repave a large stretch of a very busy road with their core crew of 15 people. The government responds that it is too much of an inconvenience to have this busy road obstructed for three months, so the job must be completed in one month. If the relationship between construction time and crew members is inversely proportional, how many crew members does the construction team need if they are to complete the job in one month? Express your answer as an integer.
