While doing a science experiment in the physics lab, Donna took 5 measurements of the temperature and wrote the average of those as an answer. If the measurements of the temperature are 1, -4, -3, 2 and 0 then what is the final answer of her experiment?
An amount of $ 7350 is made up with the notes of denominations $ 100, 50, 20, and 10. The number of $10 notes are 5 times the number of $20 notes.
