John's camera broke so he decided to rent one for 4 weeks. It was a $5000 camera and the rental fee was 10% of the value per week. His friend who was there when it broke agreed to pay 40% of the rental fee. How much did John pay?
Let's be accurate as possible and think first.
1200
The rental fee is 5000 *.

1 = $500 per week.

So it cost 500 * 4 = $2000.

His friend pays 2000 *.

4 = $800.

So he pays 2000 - 800 = $1200.

.

Therefore, the answer is 1200
