. 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) =
