small:
The answer is spot on if based on your interpretation.However, the given answer is the same as what Dharma has interpreted.
I will interpret as the both men were painting for a total duration of 5 hours, so the answer is 6 hours???
I am confused.Consider these two sentences.
Mr Yoma and Mr Ula together took 5 hours to paint a room.
Mr Yoma and Mr Ula took 5 hours to paint a room.
Do they have the same meaning in context?Or, do they mean different things? -
tianzhu:
From your question, I interprete as with both Mr Yoma and Mr Ula in a room where they (together) took 5 hrs to complete painting the whole room. That's my inpretation of your 1st sentence ...\"together took\"

Jack bought some pens and erasers for a total of $100.10.
He spent $9.10 more on the pens than the erasers.
Each pen costs $3.70 more than each eraser.
Jack bought 6 times more ereasers than pens. How much does each pen cost? -
I'm not sure if this is right, but based on my interpretation of the question:
Quantity of P:E is 1:7
P [__]
E [__][__][__][__][__][__][__]
Price of P & E (in total)
P [_______][_$9.10_] ````` } Total
E [_______] ````````````` }$100.10
By Price:
$100.10 - $9.10 = $91
2u -> $91
1u -> $45.50
Since there are 7 units of erasers, each unit of erasers will cost $45.50/7 = $6.50
The price of the pens is $45.50 + $9.10 = $54.60
Price of pens take away the price of 1 unit of erasers (to find the difference in amount if the same amount of pens & erasers were bought):
$54.50 - $6.50 = $48.10
Since each pen is more expensive than each eraser by $3.70,
$48.10/$3.70 = 13 pens
To find the price of each pen:
$54.60/13pens = $4.20 -
