Problema Solution
Shipping restrictions. The accompanying graph shows all of the possibilities for the number of refrigerators and the number of TVs that will fit into an 18-wheeler.
a) Write an inequality to describe this region.
b) Will the truck hold 71 refrigerators and 118 TVs?
c) Will the truck hold 51 refrigerators and 176 TVs?
Answer provided by our tutors
first find slope from points (110,0) and (0,330).so slope is -3
equation is y<=-3x+330
so inequality is 3x+y<=330
for part b)
put x=71 and y=118
so we get 331<=330 which is false
so truck can't hold 71 refrigirators and 118 tvs
for part c.
put x=51 and y=176
so we get 329<=330 which is true.so truck hold 51 ref and 176 TV's
