Danielle wants to leave a 15% tip on her restaurant bill. The total she pays with the 15% is $94.30. What is her restaurant bill

Vlad [161]

Answer:

$628.67

Step-by-step explanation:

15% of her restaurant bill is $94.30.

15 goes into 100, 6 2/3 times. so we multiply both 15% and $94.30 by 6 2/3 to get 100% and the restaurant bill.

15% x 6 2/3 = 100%

$94.30 x 6 2/3 =

628.666666

$628.67

I hope that this helps! :)
