a.input variable
b.output variable
c.equation

number beads=27+LengthinInches*5

a. input variable: Necklace length (in inches)

b. output variable: Number of beads needed for the necklace
c. equation:

Number of beads needed = 27 (spacers) + 5 (beads per inch) x Necklace length (in inches)

In equation form:

Beads needed = 27 + 5 x Necklace length
