a(1) = 3(1)-1 = 3-1 = 2
a(2) = 3(2)-1 = 6-1 = 5
a(3) = 3(3)-1 = 9-1 = 8
So, the sequence would be 2,5,8,11....
Hello!

Prudence would get (as an estimation or prediction,) 4 silver earrings and 2 gold.

WORK: 8+16=24
8/24=0.3333333
16/24=0.6666667
4/6=0.6666667
2/6=0.33333333

Hope this helps and have a great day!
1.
If no changes are made, the school has a revenue of :
625*400$/student=250,000$
2.
Assume that the school decides to reduce n*20$.
This means that there will be an increase of 50n students.
Thus there are 625 + 50n students, each paying 400-20n dollars.
The revenue is:
(625 + 50n)*(400-20n)=12.5(50+n)*20(20-n)=250(n+50)(20-n)
3.
check the options that we have,
a fee of $380 means that n=1, thus
250(n+50)(20-n)=250(1+50)(20-1)=242,250 ($)
a fee of $320 means that n=4, thus
250(n+50)(20-n)=250(4+50)(20-4)=216,000 ($)
the other options cannot be considered since neither 400-275, nor 400-325 are multiples of 20.
Conclusion, neither of the possible choices should be applied, since they will reduce the revenue.
20+6x=32
subtract 20 from 20 and 32
6x=12
6x/6=12
6 cancels out
x=2
Answer:
355.83 yd²
Step-by-step explanation:
A = (B + b)h/2
A = (21.6 yd + 19.3 yd)(17.4 yd)/2
A = 355.83 yd²
