Answer 1

Answer:

Cost of one package of tulips bulbs: $\ 5$

Cost of one bag of daffodil bulbs: $\ 16$

Step-by-step explanation:

Let be "t" the cost in dollars of  one package of tulips bulbs and "d"  the cost in dollars of one package of bag of daffodil bulbs.

Set up a System of equations:

$\left \{ {{3t+7d=127} \atop {12t+14d=284}} \right.$

You can use the Elmination Method to solve the system of equations:

1. Multiply the first equation by -2.

2. Add the equations.

3. Solve for "t".

Then:

$\left \{ {{-6t-14d=-254} \atop {12t+14d=284}} \right.\\........................\\6t=30\\\\t=\frac{30}{6}\\\\t=5$

 4. Substitute the value of "t" into any original equation and solve for "d":

$3(5)+7d=127\\\\7d=112\\\\d=\frac{112}{7}\\\\d=16$
