// For x 5 stars, and 1 1 star, the average is:
Ave = (5x + 1) / (x + 1)
// Solve for x to get the number of 5 stars needed to achieve this Ave with 1 star:
5x + 1 = (Ave)x + Ave
(5 - Ave)x = Ave - 1
x = (Ave - 1) / (5 - Ave)
// So to get Ave = 4.75, with 1 1-star, you need:
x = 15 5 stars
// And to get Ave = 4.5, you need:
x = 7 5 stars
// Say you have one 5-star and one 1-star. What’s the average?
(1 + 5) ÷ 2 = 3 stars! // How horrible!
// Then you get another 5-star review. Your new average:
(1 + 5 + 5) ÷ 3 = 3.7 stars. // Getting better.
/* So you could just keep adding another 5 and increasing the number after the ÷ until you hit 4.5.
As Mark says, 7 5-star reviews is the magic number to get back up to four and a half: */
(1 + 5 + 5 + 5 + 5 + 5 + 5 + 5) ÷ 8 = 4.5
