the highest test score scott can receive is a 100.The sum of his first four test scores is atleast 360.Find the range of scores scott must get on his fifth test to have an average greaterthan 70?

(360+S)/5=70 so
S=360-350 which means he can get as low as -10 and get a 70 average. Now his teacher may not give minus scores, so he can score zero to 100 and get his 70 average.
