Question 766287: 1. The EdHelper Florist sells roses at $12.24 a bunch, tulips at $3.25 a bunch, and daffodils at $6.12 a bunch. Jose ordered a banquet of 29 bunches of roses and tulips. If he wants to spend exactly $130.21, how many bunches of each can he buy?
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?

You can put this solution on YOUR website! 1. The EdHelper Florist sells roses at $12.24 a bunch, tulips at $3.25 a bunch, and daffodils at $6.12 a bunch. Jose ordered a banquet of 29 bunches of roses and tulips. If he wants to spend exactly $130.21, how many bunches of each can he buy?
--------------------
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)
