    Answer:

    Michelle purchased 70 tomato plants and 60 bell pepper plants.

    Step-by-step explanation:

    Lets create a system of equations. Lets substitute x for the amount of tomato plants and y for bell pepper plants.

    x+y=130

    1.50x+2y=225

    Lets use the substitution method.

    Isolate y.

    y=130-x

    Substitute 130-x for y in the second equation.

    x1.50+2(130-x)=225

    Use the distributive property.

    1.50x+260-2x=225

    Combine like terms.

    -0.5x+260=225

    Subtract 260 on both sides.

    -0.5x=35 or 0.5x=35

    Now divide both sides by -0.5. Remember that dividing by a decimal or fraction actually multiplies by the reciprocal. So 35 divided by 1/2 would equal 35 multiplied by 2/1.

    x=70

    Substitute x in the equation to solve for y.

    1.50(70)+2y=225

    Multiply.

    105+2y=225

    Subtract 105 on both sides.

    2y=120

    Divide both sides by 2 to isolate y.

    y=60

    X is equal to 70 and y is equal to 60.

    Just to check, substitute our known values for variables.

    1.5(70)+2(60)=225

    Multiply.

    105+120=225.

    Add.

    225=225. Its correct!

    Hope this helps!
