Answer:
4
Step-by-step explanation:
4+15-3=16 (the total amount plus coupon)
16/4=4 (divided by 4 to find out how much each friend pays)
A1=8
common ratio=r
sum of 6 terms
S=a1+a2+a3+...+a6
=a1(1+r+r^2+...+r^5)
=a1(r^6-1)/(r-1)
but we're given S=74648
=>
8(r^6-1)/(r-1)=74648
Cross multiply and solve for r (by trial and error)
r^6-1=9331(r-1)
r=6
so
a(3)=a1*r^(3-1)
=8*(6^2)
=288
I think answer should be d. Please give me brainlest I hope this helps let me know if it’s correct or not
The Answer is B.
2.97/8= .371
3.25/10= .325
4.10/12= .342
5.80/16= .366
This means you can get 1 board for $0.325 when buying 10 boards.
