    Chocolate thickshakes will cost $5 and fruit smoothies will cost $3. Let's say the cost of chocolate thickshakes are x and the cost of fruit smoothies are y.

    3x + 4y = 27

    3x + 3y = 24

    3 (2+s) + 4s=27 the answer is $3 for smoothies and $5 for the thick shakes

    Step-by-step explanation:

    Let say t is for thick shake, s is for smoothies

    (2+s) = t

    Jake pays $27 for 3 thick shakes and 4 smoothies

    Then you plug in the information

    3t+4s=27

    Since we have what thick shakes equals 2+s

    3 (2+s) + 4s=27

    then simplify

    6+3s+4s=27 Combine like terms

    6+7s=27 Do the inverse operation - 6 on both sides

    7s=21 The divide by 7 to get s by itself

    3=s is for the smoothies

    Then plug back in s to find the vaule of the thick shakes

    2+3=t

    5=thick shake
