This is what it looks like.
Assuming the cost of a bag of popcorn is p and that of candy bars is b, then;
Troy ; 28p +40b = 282
Jake; 17b + 20b = 160.50
Solving the two equations simultaneously,
20(28p +40b =282)
40(17p + 20b =160.5)
we get;
560p +800b = 5640
680p + 800b = 6420 subtracting to eliminate b;
-120p= -780
p = 6.50
Replacing the value of p in either equation to get b;
17 (6.5) +20b =160.5
20b = 50
b = 2.50
Therefore the cost of a bag of popcorn is 6.50
Answer:

Step-by-step explanation:
That’s poor because every number multiply by one is the same number
3*1: 3
Answer:
Therefore Area of Rectangle IJKL is 108 unit².
Step-by-step explanation:
Given:
The vertices of a Rectangle are
I ( 6 , 8)
J ( 6 , -1)
K ( -6 , -1)
L ( -6 ,8)
To Find:
Area of Rectangle IJKL= ?
Solution:
First we will find the Length and Width of Rectangle by Distance Formula ,
Substituting the values we get
Similarly for JK we will have,
Now
Now Area of Rectangle is given by
Substituting the values we get
Therefore Area of Rectangle IJKL is 108 unit².
