Please help ASAP. I've been stuck on this question for 5 days!

Suppose the interest rate rises so that microcredit program participants must make payments of 35 rather than 30 in periods 1 and 2. Now who participates and which projects do they undertake?

Project Description		Setup cost	Profits delivered by business in each of three periods
			Period 1	Period 2	Period 3
Purchase inventory for small retail operation	Low skill	50	25	25	0
	High skill	50	40	40	0
Purchase sewing machine for tailoring business	Low skill	70	0	0	0
	High skill	70	0	60	60

Impact on average consumption for:	Participate (yes or no)	Period 1	Period 2	Period 3
Group 1		0	0	0

Group 3		-50	30	60
