Mark and julio are selling flower bulbs for a school fundraiser. customers can buy bags of windflower bulbs and packages of crocus bulbs. mark sold 2 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $105. julio sold 9 bags of windflower bulbs and 5 packages of crocus bulbs for a total of $164.50. find the cost each of one bag of windflower bulbs and one package of crocus bulbs. solve having substitution method.

Bag of windflower bulbs costs $8.50

Package of crocus bulbs costs $17.60

Step-by-step explanation:

Let $x be the price of one bag of windflower bulbs and $y be the price of one  package of crocus bulbs.

1. Mark sold 2 bags of windflower bulbs for $2x and 5 packages of crocus bulbs for $5y. In total he earned $(2x+5y) that is $105. So,

2x+5y=105

2. Julio sold 9 bags of windflower bulbs for $9x and 5 packages of crocus bulbs for $5y. In total he earned $(9x+5y) that is $164.50. So,

9x+5y=164.50

3. You get the system of two equations:

From the first equation

Substitute it into the second equation:

9x+105-2x=164.50

7x=164.50-105

7x=59.5

x=$8.50

So,

5y=105-2·8.5

5y=105-17

5y=88

y=$17.60

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
