    Answer: Allysa purchased 4 Americana chickens and 8 Delaware chickens✔️

    Step-by-step explanation:

    From the information they provide us, we have to establish the necessary equations to solve the problem.

    Let A be the American chickens and D be the Delaware chickens.

    Allysa purchased 12 chickens:

    A + D = 12 } Equation 1

    Americana chickens cost $3.75 each and Delaware chickens cost $2.50 each. Allysa spent $35:

    $3.75A + $2.50D = $35 } Equation 2

    We take the value of A from equation 1 and substitute it into equation 2:

    A = 12 - D } Equation 1

    $3.75A + $2.50D = $35 } Equation 2

    $3.75 (12 - D) + $2.50D = $35

    $3.75·12 - $3.75D + $2.50D = $35

    $45 - $3.75D + $2.50D = $35

    $45 - $35 = $3.75D - $2.50D

    $10 = $1.25D

    D = $10/$1.25 = 8, Delaware chickens

    A = 12 - D = 12 - 8 = 4, Americana chickens

    Answer: Allysa purchased 4 Americana chickens and 8 Delaware chickens✔️

    Check

    We can substitute these values in the equation 2

    $3.75A + $2.50D = $35 } Equation 2

    $3.75·4 + $2.50·8 = $15 + $20 = $35 ✔️Checked!
