For this case, the first thing we must do is define variables.
We have then:
x: number of hands
y: number of fingers
We have then that the equation that models the problem is given by:
[tex] y = 5x
[/tex]
For 6 hands we have:
[tex] y = 5 (6)
y = 30
[/tex]
Answer:
The number of fingers that Tim should say is 30
