    Answer:$10.625

    Step-by-step explanation:

    5x+3y=80.25

    x+y=19.75 ; x=19.75 – y

    5(19.75-y) +3(y)=80.25

    98.5-5y+3y=80.25 ; -2y= -18.25

    y= 9.125 or y= 9.13

    x+9.125= 19.75 ; x= 10.625

    given that x is a pepperoni pizza and y is a cheese pizza,

    a pepperoni is 10.625 rounded to how the question/examiner wants it rounded, and a cheese pizza is 9.125 respectively.
