They bowled for 3 hours and spent $7.
(I have no Idea how to make a graph on this website, so I can't help you there, sorry)
Let x = number of hours
Tucker: 2x+1
Blanca: x+4
2x+1 = x+4
x=3
For the graphs your lines should have equations like this:
y= 2x+1
y=x+4
The point of intersection of these lines should be at point (3,7)
Okay, so let's make a sample space where in one section, one toy is the leader of each group for as many possibilities as there are.
T K E
T E K
K E T
K T E
E T K
E K T
There are 6 possibilities, and so each arrangement has a 1 over 6 chance of being used.
