When the going rate is $10.00 per hour, Ann wants to babysit 6 hours each week and Pat wants to babysit 4 hours each week. If the rate goes up to $12.00, Ann and Pat both double the number of hours they are willing to babysit each week. Based on this information, a combined supply curve will pass through the points:
A) price = $10.00, quantity supplied = 20 and price = $12.00, quantity supplied = 10.
B) price = $10.00, quantity supplied = 10 and price = $12.00, quantity supplied = 20.
C) price = $10.00, quantity supplied = 6 and price = $12.00, quantity supplied = 4.
D) price = $10.00, quantity supplied = 4 and price = $12.00, quantity supplied = 6.
