    Answer:

    3 Vases

    4 Mason jars

    Step-by-step explanation:

    The vase costs $12 and the mason jar costs $8. She has $72 to spend. We know that she must at least buy 7 containers. Let vase be x₁ and mason jar x₂. We have two equations:

    [tex]x_1+x_2=7[/tex]

    [tex]72=12x_1+8x_2[/tex]

    WE can solve the value by substitution:

    [tex]x_1=7-x_2[/tex]

    [tex]72=12(7-x_2)+8x_2[/tex]

    [tex]x_2=3[/tex]

    Therefore:

    [tex]x_1=7-3=4[/tex]
