Answer:
B
Step-by-step explanation:
Note the common difference between consecutive terms of the sequence.
d = 16 - 12 = 20 - 16 = 4
This indicates the sequence is arithmetic with sum to n terms
= 
[2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 12 and d = 4, thus
= 
[ (2 × 12) + (41 × 4) ]
= 21( 24 + 164) = 21 × 188 = 3948 → B
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
There could be collinear but need to be on the same plane
