A sports shop sold tennis rackets in 4 different weights, 3 types of string, and 3 grip sizes. How many different rackets could they sell

36

Step-by-step explanation:

Given that:

Weights of racket available = 4

Strings of racket options = 3

Grip size option = 3

The different racket types they could sell will be :

Weight option * string option * grip size option

4 * 3 * 3 = 36 different racket types.

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers
