the room charge for a hotel is 230$ each day. the estevez family spends 4 days on vacation at the hotel . at the end of their stay they leave a 10% tip of the total room bill for the person who cleans their room. how much is the total bill including the tip for the person who cleans the room? explain

Answers

It's 230 per day and they spend 4 days so multiply 230 × 4 = 920

920 is the room charge. Now multiply 920 × 10% for the tip.

920× .10 = 92 that's the top

Add the tip to the room charge

920 + 92 = $1,012

10% of 230 is 23 so
230
+23 =
253
