Question

Mrs. Schmidt overlooked a bill andhad to pay a $15.00 late fee. Thetotal of the bill and the late feewas $90.00. About what percentof the grand total was the late fee?

Answer 1

the total of, bill + late fee = 90 $

also, late fee = 15 $

put the values,

bill + 15$ = 90 $

bill = 90 - 15

bill = 75 $

let the late is x percent of grand total,

$90\times\frac{x}{100}=15$$\begin{gathered} x=\frac{1500}{90} \\ x=16.66\text{ \%} \end{gathered}$

thus, the answer is 16.66 %

after rounding off

the answer is 17 %
