First you divide the cost per the number of units (6):
$2.76/6=$0.46
Then you multiply the unitary cost per 15:
$0.46x15=$6.90 (this is the cost of a 15-pack)
Answer: Choice B (If you need to do questions like this in the future i recommend using the desmos graphing calculator online, inputting the equations and comparing them)
The answer is b.5 because 5 x 4 is 20 and g is 20
32 (forwards) /16 (team's) =2 forwards on each team 80 (gaurds) / 16 (team's) =5 gaurds on each team
