Answer:
D
Step-by-step explanation:
Let x be the first batch
let y be the second batch
y=2x
His brothers each received 9 rolls from the second batch i.e. 9×4=36
So
2x= 36+ (10÷6)x
2x - (10÷6)x = 36
12x-10x = 216
x=108
and y= 2 × 108= 216
Answer:
882
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 18 and d = 30 - 18 = 12, thus
= 18 + (72 × 12) = 18 + 864 = 882
