c.
Assume that Sn is valid for n = k
b.
Verify that Sn is valid for n = 1
d.

goog may have it for you

the equivalent expression are always the hardest ones but you look at the gcf also

step-by-step explanation:

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540
