Dan and shanice are selling flower bulbs for a school fundraiser. Customers can buy bags of windflower bulbs and packages of crocus bulbs. Dan sold 5 bags of windflower bulbs and 6 packages of crocus bulbs for a total of $151. Shanice sold 4 bags of windflower bulbs and 3 packages of crocus bulbs for a total of $92. What is the cost each of one bag of windflower bulbs and one package of crocus bulbs?

Respuesta :

Answer:

The cost of one bag of windflower is [tex]11\[/tex] and one bag of crocus is [tex]16\[/tex]

Solution:

Let windflower bulbs be x and crocus bulbs be y.

Sales by Dan is 5 bags of windflower bulbs and 6 packages of crocus bulbs for 151,

i.e. [tex]5x+6y=151[/tex]

[tex]6y=151-5x ----- (1)[/tex]

Sales by Shanice is 4 bags of windflower bulbs and 3 packages of crocus bulbs is 92,

i.e. [tex]4x+3y=92 ----- (2)[/tex]

Here we are eliminating the value of y so that we can find the value of x,

The least common multiple of the coefficients of y (6 and 3) is 6.

[tex]\therefore[/tex]multiplying (2) by 2 on both sides we get,

[tex]2\times(4x+3y)=2\times92[/tex]

[tex]8x+6y=184[/tex]

[tex]6y=184-8x ----- (3)[/tex]

On equating (1) and (3) we get,

[tex]184-8x=151-5x[/tex]

On grouping the terms,

[tex]184-151=-5x+8x[/tex]

[tex]33=3x[/tex]

[tex]x=\frac{33}{3}[/tex]

[tex]x=11[/tex]

On substituting the value of x in (2) we get,

[tex]4\times11+3y=92[/tex]

[tex]44+3y=92[/tex]

[tex]3y=92-44[/tex]

[tex]3y=48[/tex]

[tex]y=\frac{48}{3}[/tex]

[tex]y=16[/tex]

Hence, the cost of one bag of windflower bulb is 11 and one bag of crocus bulb is 16.
