Question 329314
A tentmaker had 4500 square yards of nylon material. it takes 45 sq yards of nylon to make an 8x10 tent and 50 square yards to make a 9x12 tent. to model this situation the manager wrote the equation 45x+50y=4500. 
What do x and y represent?
x is the number of 8x10 tents; y is the number of 9x12 tents.
----------------------- 
Graph the equation.
45x+50y = 4500
9x+10y = 900
y = (-9/10)x + 90
{{{graph(400,300,-10,150,-10,150,(-9/10)x+90)}}}
----------------
 
How many solutions are there to the equation given that the number of tents of each type must be a whole number.
x = 0, 10,20,30,40,50,60,70,80,90
Ans: 10 solutions
