Answer:
If an equal number of each brand was ordered, how many dozens of each brand were ordered?
Step-by-step explanation:
in order to determine the number of balls purchased, we must first determine the difference in price between them = $2 - $0.90 = $1.10
since the total difference in price was $660 and an equal number of balls were purchased, then the number of balls purchased = $660 / $1.10 = 600 balls
to determine the number of dozens purchased of each brand we just divide 600 by 12 = 50 dozens
Step-by-step explanation:
3k + 2k - 6 = 8k + 3

8k - 5k = -9
3k = - 9
k = - 9/ 3
K = - 3
