Answer:
The total cost is [tex]\$168[/tex]
Step-by-step explanation:
Let
x-----> the number of tulips
y-----> the number of daffodils
C-----> the total cost
we know that
[tex]x=24\ tulips[/tex]
[tex]y=2x[/tex]
substitute the value of x
[tex]y=2(24)=48\ daffodils[/tex]
Find the total cost
[tex]C=3x+2y[/tex]
substitute
[tex]C=3(24)+2(48)=\$168[/tex]
