--------------------
Equations:
Quantity Eq: r + t + d = 29
Value Eq::::12.25r + 3.25t + 6.12d 130.21
----
Note: You have three variables. You need another equation statement
to solve for r, t, and d.

3. Peanut butter costs sixteen cents an ounce. Jelly costs two hundred twenty four cents per pound. Hailey wants to make 1 1/2 pounds of peanut butter and jelly. If she wants the entire mix to cost $3.52, how many pounds of jelly should she use?
-------
Value Eq::: 0.16p + 2.24j = 3.52
Quantity::: p + j = 3/2 lbs
-------
Modify for elimination:
16p + 224j = 352
16p + 16j = 24
-----
Subtract and sole for "j":
208j = 328
---
j = 1.58 lbs (amt. of jelly needed)
