Nearest Hour

Question

Seems too easy. Am I missing something?

 

Alba's face painting charges a flat rate of $50.00 for set up and travel and an additional $60.00 per hour for the face painting service. Cathy's bill for Linda's birthday party was just over $450.00.  How long to the nearest hour was Alba providing face painting for Linda's party?

 

So I deduct the 50.00 flat rate to determine how many hours: 450.00 - 50 = 400/60 = 6.66 hours. So 7 hours?

 

I think the "just over" $450.00 and rounding to the nearest hour is confusing me. 

Answer 1

With information given, sounds right to me...   That "just over" wording needs to be more clear.  I'd challenge the question if anyone says you wrong. 

Answer 2

450< 50 + 60h

400 < 60h

6 2/3 < h

So rounded to the nearest hour is ?
