Question

You and your family go to dinner at a local restaurant in Rexburg, Idaho and your online banking report shows that the total dinner bill (food, tax, and tip) was for \$33. Suppose that you did not keep your receipt, but you remember you paid a 15% tip for the service. What was your bill prior to calculating the tip (that is, for food and tax only)?

\$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
