Question

Justin had $49 before spending n dollars on Jeans. How much money remains? Translate to an algebraic expression

Answer 1

49 - n = ?

Answer 2

Let n^1=Dollar spend on Jeans
Let n^2=Remaining money

Now,49-n^1=n^2
49=n^2+n^1
49-n^1=n^2
=49-n^1-n^2
=49-2n
2n=49
n=49/2
=$24.5

therefore,The total money remains=$24.5
The Money spend on jeans=$24.5
