1.	A family has a monthly net pay N which is 70% of their gross monthly pay G. They decided to subtract their monthly food allowance of $350 from their monthly net pay and invest 5% of the remainder. Write an equation for the investment each month I, given the above restrictions.
		A.	I = 0.95(0.7G - 350)	B.	I = 0.95(0.3G - 350)
		C.	I = 0.05(0.3G - 350)	D.	I = 0.05(0.7G - 350)
