. Amanda and Ndiba are selling flower bulbs for a school fundraiser.
Customers can buy packages of tulip bulbs and bags of daffodil bulbs.
Amanda sold 6 packages of tulip bulbs and 12 bags of daffodil bulbs for a total of $198.
6t + 12d = 198
Ndiba sold 7 packages of tulip bulbs and 6 bags of daffodil bulbs for a total of $127.
7t + 6d = 127
Find the cost each of one package of tulips bulbs and one bag of daffodil bulbs.
:
Use elimination here, multiply the 2nd equation by 2, subtract the 1st equation
14t + 12d = 254
6t + 12d = 198
------------------subtraction eliminates d, find t
8t + 0 = 56
t = 56/8
t = $7 for tulips
Find d using the 1st equation, t=7
6(7) + 12d = 198
42 + 12 d = 198
12d = 198 - 42
d = 156/12
d = $13 for daffodils

You can check these solutions in the original 2nd equation
7(7) + 6(13) =
