:1.- + y + z = tutal investment. I]. use: + a. as; + u. are = annual return 3:]: — y = [I 7. When the tetal investment is $40,000 and the annual return is $2,525,
find the ameunt invested in eaeh bend. x=I
y=I
z=I 8. When the tetal investment is $200,000 and the annual return is $13,300, find
the amount invested in each bend. x=I
y=I
z=I
