If xy=0
assume that at least x or y=0
3(x-3)=0
therefor
3=0 or x-3=0
3=0 is false
therefor
x-3 mus equal zero
x-3=0
add 3 to both sides
x=3
x6+50=320
-----------------
x6=50-50=320-50
x6=270
x6/6=270/6
x=45
So this person is spending $45 a month.

(i) interest = $1680
(ii) total amount = 13680

=13680
They are all paralellograms
That already is rounded to the nearest tenth
