<u>Kenny</u>
<em>See attachment for complete question</em>
Required
Determine the amount for 2x and 3y
From Jamal's and Kenny's orders we have:
--- (1)
--- (2)
Multiply (1) by 3
![3 * [3x + 2y = 4.85]](https://tex.z-dn.net/?f=3%20%2A%20%5B3x%20%2B%202y%20%3D%204.85%5D)
--- (3)
Subtract (2) and (3)
Solve for x
Substitute in
Solve for y
So, the cost of 2x and 3y is:
