increase her profit, as expressed by the function y = 45x, where x is the number sold and y is the amount of profit. How many more dollars will Amanda earn on each cake if she switches to the new material? Explain how you found your answer. (5 points)
Nancy's rate=27 mph Greg's rate=45 mph t=Greg's time t+2=Nancy's time Since they both traveled same distance then: 27(t+2)=45t 27t+54=45t 18t=54 t=3 hours Greg will pass Nancy after 3 hours
