Question:

every book in our store has a rating so that customers can sort through selections. In this task, declare a variable named rating and assign the value 7.5

Code:

let title = "A Dance with Dragons"

var rating = "7.5"

doesnt work...

help please

The answer is:

var rating: Double = 7.5;

P.S Don't forget to add the colon sign ":", behind var name (in this case "rating"), then declare the type of the variable (in this case the "Double" variable), and then add a value (in this case "7.5"), so be sure you add a semicolon sign ";" behind that value. Hope this was helpful. All the best,

Hi there! Take a look again. You're assigning the string value "7.5" instead of the numerical value 7.5. Try it again without the quotation marks :sparkles:
