Information about girls' ice skates:

Colors: white, beige, pink, yellow, blue

Sizes: 4, 5, 6, 7, 8

Extras: tassels, striped laces, bells

Assuming that all skates are sold with ONE extra, how many possible arrangements exist?

a) 25

b) 50

c) 75

d) 125

Answer: c) 75

There are 75 possible arrangements exist.

Step-by-step explanation:

Given : The number of choices for Colors = 5

The number of choices for Sizes = 5

The number of choices for Extras = 3

WE assume that all skates are sold with ONE extra.

Then by Fundamental counting principle, the total number of different possible arrangements exist = (number of choices for Colors) x (number of choices for Sizes) x (number of choices for Extras)

= 5 x 5 x 3 = 75

Hence, there are 75 possible arrangements exist.

Thus, the correct answer is c) 75.
