Add Values if Checkbox is checked

Hello there,

I would like to add up values of certain cells if their corresponding check box is checked.
Here is the arrangement of the columns and values.

Column A-C: Not needed for the calculation
Column D: Price in €, D2-D5 have the following: 33.06, 32.12, 90.68 and 17.60
Column E: Checkbox

Now, I have a row for the total of these values. How would the formula be?
e.g. Checkboxes E2, E3 and E4 are checked, E5 is not. The total would be €155.86.

Thank you for your help.
