Question

a clothing store is raising the prices of all its sweaters by $ 3.00. write an expression that could be used to find the new price of a sweater that originally cost d dollars?

Answer 1

The expression would be d + 3.

You're raising $3 in every sweaters cost so d is the cost of the sweater and you add 3 to raise $3 in the price.

Hope this helps :)
