    Answer:

    pizza = £2.25

    drink = £1.15

    Step-by-step explanation:

    Shamirah and friends= 4p+7d=£17.05

    James and friends=3p+5d=£12.50

    21p+35d=87.50

    20p+35d=£85.25

    subtract

    p+0=2.25

    add value to original

    (4*2.25)+7d=17.05

    9+7d=17.05

    -9          -9

    7d=8.05

    d=1.15

    values of p and d

    p = £2.25

    d = £1.15
