Problema Solution
The function w= 30 - (3/4)n represents the weight w in pounds of the papers in Tyrone's newspaper delivery bag after he delivers n newspapers. Find the zero and explain what it means in the context of this situation.
Answer provided by our tutors
if n = 0, the w=30, indicating that a full load of papers weighs 30 pounds
-(3/4)n indicates that each paper weighs 3/4 pounds
0 = 30-(3/4)n
n = (4*30)/3 = 40
a total of 40 papers are in Tyrone's bag, so after 40 papers have been delivered his bag is empty
