We use the same double angle identity.
Find the unit price (price per bottle)
$3.79 ÷ 6 = $.63 a bottle (approximately)
$4.50 ÷ 9 = $.50
$6.89 ÷ 12 = $.57 (approximately)
So your best bet is the 9 pack.
You will find that sometimes your best value is not to buy the greatest amount of a product.

So James covers 8 meters in the first second....then he sprints 9 meters per second......
9 seconds after the race....so there are 8 seconds that he is sprinting 9 meters per second.....(8 * 9) = 72 meters....plus the 8 meters for the 1st second = (72 + 8) = 80 meters....
and if it is 100 meter race, and he has ran 80 meters, then that leaves 20 meters from the finish line....answer is D
