4. Is your answer to question 3 the real solution or an extraneous solution? Explain how you know. 5. The giant gumball machine will dispense gumballs that are 1" in diameter. To the nearest gumball, how many will fit in the globe? You can round your final answer to the nearest whole number. 6. Once the new machine is installed, the cost per gumball will be $0.25. If, during the first month, 20% of the gumballs in the machine are sold, how much money will the candy store earn? Assume the gumball machine was initially filled to capacity. Show your work. 7. Six months after it is installed and filled to capacity, the giant gumball machine must be emptied for cleaning. At that time the gumballs left in the machine are thrown away. If 83% of the original number of gumballs were sold, and the gumballs cost the candy store $0.10 each, how much money will the store lose when cleaning the machine
