a.Write a system of inequalities that describes this situation.
b.Graph the system to show all possible solutions.
Answer provided by our tutors
let
x = lb of flour
y = lb of cornmeal
You want to spend less than $9.50 on flour and cornmeal:
1.50x + 2.50y < 9.50
and you need at least 4 lb altogether:
x + y >= 4
a. the system of inequalities that describes this situation:
1.50x + 2.50y < 9.50
x + y >= 4
