Answer:
To solve this you assign $x for the cost i yd of flannel and $y for the cost 1 Yd of calico
Your Equations now become:
Joan---3x+4y=25
Chris----x+2y=11
Multiply Chis's purchase by 3
3x+6y=33
Subtract Joan's from this new equation
0+2y=8
y=8/2 and from Chris's Equation x=3
y=4 which is the Price of 1 yard of calico
The Price of 1 yard of Calico is $4.00
Check for Joan:3.3+4.4=25
9+16=25
Check for Chris:1.3+2.4=11
3+8 =11
