As ordered pairs ( g , C ) where g is the number of games and C is the cost
( 5, 20.50) and ( 9, 28.50)
the slope M = ( 28.50 - 20.50 ) / (9-5)
= 8/4
= 2
So the slope M=$2 per game
Using (5, 20.50)
The intercept B = y - m* g
= 20.50 - 2 * 5
= 20.50 - 10
= 10.50
So the fixed base cost, or FLAT RATE is $10.50.
That is if they played ZER0 games, they still have
to pay $10.50 just to get in.
The linear function is C (g) = 2*g + 10.50
Equal groups means that different items will be divided in groups with the same number of items in it.
Example: we have 3 bananas and 5 apples. Finding the smallest common multiple<span> of the two integers 3 and 5, the </span>least common multiple (LCM) will give us the number of items that every group should have.
The LCM is 15.
We will have 15/3=5 groups of bananas with 3 bananas in each and 15/5=3 groups of apples with 5 apples in each.
You should get something like this
