Question 1031501
A restaurant manager wants to purchase 200 
sets of dishes. One design costs ​$15 per​ set, while another costs ​$45 per set. If she wants to use her entire budget of ​$5700​, how many of each design should be​ ordered? 
------
Quantity Eq:: f + t = 200 sets
Value Eq::  15f + 45t = 5700 dollars
-----------------------------------
Modify for elimination::
f + t = 200
f + 3t = 380
----------------------
Subtract and solve for "t"::
2t = 180
t = 90 (# of sets of $45 sets to buy)
f = 200 - 90 = 110 (# of $15 sets to buy)
