Let J(d) represent the amount of money Janelle has left. Then:
J(d) = $265 - d, where d is the price paid for that sweater.
The expression which is used to represent the amount of money left with Janelle is:
$ (265-d)
The amount of money that Janelle has saved before the purchase is: $ 265
Also, she bought a sweater for d dollars.
This means that now d dollars amount will be deducted from the amount which she has saved before the purchase.
Hence, the amount she will be left with is: $ (265-d)
