The equation for women’s shoe sizes is y = 3x − 21, where x is the length of the foot in inches. What shoe size should you recommend to a woman whose foot is 8.5 inches long?

Using the equation y = 3x − 21; where x is the length of the foot in inches, we can calculate the recommended shoe size by substituting the value of x. Given that a woman's feet is 8.5 inches long.
y = 3x − 21
y = 3(8.5) − 21
y = 25.5 − 21
y = 4.5
I will recommended a shoe size of 4.5.
