Answer:

8 lilies and 12 tulips flowers

Step-by-step explanation:

Let x be the lilies and y be the tulips flower.

Given:

Total flowers = 20

Lilies cost = $3

Tulip cost = $2

Bouquet cost = $48

Solution:

A bouquet of lilies and tulips has 20 flowers, so sum of the lilies and tulip flower is equal to 20 flower,

[tex]x+y =20[/tex] -----------------(1)

Since lilies cost $3 each, tulip cost $2 each and bouquet cost is equal to $48, so we write the equation as.

[tex]3x+2y=48[/tex] ------------------(2)

From equation 1.

[tex]x=20-y[/tex] --------------(3)

Substitute [tex]x=20-y[/tex] in equation 2 and simplify.

[tex]3(20-y)+2y=48[/tex]

[tex]60-3y+2y=48[/tex]

[tex]60-y=48[/tex]

[tex]y=60-48[/tex]

[tex]y=12[/tex]

Substitute [tex]y=12[/tex] in equation 3.

[tex]x = 20-12[/tex]

[tex]x=8[/tex]

Therefore, 8 lilies and 12 tulips flowers in the bouquet.
