Shelley's mom bought a pair of shoes for $40.00. the tax on the shoes was 5%.how much did shelley's mom pay in tax? how much was her total bill?

There is a $2 tax and the total bill is $42.

Step-by-step explanation:

5/100 = x/40

X= 2

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
