    Answer:

    $28.7

    Step-by-step explanation:

    From the date given, the total cost of the bill(food+tax+tip)=$33.

    let express the above in mathematical form,

    food=f,

    tax=t,

    tip=x

    hence f+t+x=$33

    let f+t=y  (y=bill for food and tax)

    hence

    x+y=$33…….equation 1

    since the tip paid is 15% of the total bill, hence

    x=15%(y)——-equation 2

    if we substitute equation 2 into equation 1 we arrive at

    15%y+y=$33

    0.15y+y=$33

    1.15y=$33

    y=33/1.15

    y=$28.7

    Hence the bill for the food and tax only is $28.7
