Write a verbal description for the algebraic expression 3m-8n 13

The given expression is

Notice that the main operation is a quotient. So, we must begin with that.

Now, the quotient is between a difference at the numerator and a number at the denominator.

Then, notice that the difference is between the triple of a number and 8 times another number.

So, the full statement would be

"A quotient between the difference of the triple of a number and 8 times another number, and 13".

Another way would be

"The triple of a number subtracted by 8 times another number, all divided by 13".

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
