It’s saying my profit value is incorrect

script.js 
var wholesalePrice = 5.45;
var retailPrice = 9.99;
var quantity = 47;
var salesTotal = retailPrice * quantity 
var profit = (salesTotal - wholesalePrice)* quantity;

By grouping the subtraction, you caused it to happen before the multiplication. But "salesTotal" already has the "quantity" multiplied in, so you'll want to multiply only the "wholesalePrice".

Remove the parentheses and the operator precedence will cause the multiply to be performed first.
