Let the number of pounds of Cantaloupes bought by Sally = y
---------------------------------(1)
Moreover,
---------------(2)
Solving (1) and (2) by substitution:
![\[x = 7 - y\]](https://tex.z-dn.net/?f=%5C%5Bx%20%3D%207%20-%20y%5C%5D)
=> ![\[2.5 *(7-y) + 2.25 y = 16.75\]](https://tex.z-dn.net/?f=%5C%5B2.5%20%2A%287-y%29%20%2B%202.25%20y%20%3D%2016.75%5C%5D)
=> ![\[17.5 - 2.5y + 2.25 y = 16.75\]](https://tex.z-dn.net/?f=%5C%5B17.5%20-%202.5y%20%2B%202.25%20y%20%3D%2016.75%5C%5D)
=> ![\[0.25y = 0.75\]](https://tex.z-dn.net/?f=%5C%5B0.25y%20%3D%200.75%5C%5D)
=> ![\[y = 3\]](https://tex.z-dn.net/?f=%5C%5By%20%3D%203%5C%5D)
From (1), x = 7-3 = 4
Profit will be 36 for 2007
