When the going rate is $2.00 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 $4.00, 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 = $2.00, quantity supplied = 20 and price = $4.00, quantity supplied = 40.
b) price = $2.00, quantity supplied = 10 and price = $4.00, quantity supplied = 20.
c) price = $2.00, quantity supplied = 6 and price = $4.00, quantity supplied = 4.
d) price = $2.00, quantity supplied = 4 and price = $4.00, quantity supplied = 6.
