    Ice Cream is 155 calories

    Cake is 445 calories

    Step-by-step explanation:

    Step 1: Make an equation

    3c - 20 = p

    p + c = 500

    Step 2: Solve the system of equations

    p = 3c - 20

    3c - 20 + c = 620

    4c - 20 + 20 = 620 + 20

    4c / 4 = 620 / 4

    c = 155

    p = 3 (155) - 20

    p = 465 - 20

    p = 445

    Ice Cream is 155 calories

    Cake is 445 calories
