Answer:
D. 100
Step-by-step explanation:
IF
2=5 ;
3=9 ; 3*5 - 3*2
4=48 ; 4*9 + 4*3
5=220 ; 5*48 - 5*4
6=1,350 6*220 + 6*5
7= 9408 7*1350 - 7*6
THEN 8 = 8*9408 + 8*7 = 75320
Each group of 2 nickels and 1 quarter has a value of $0.35. Rachelle has $6.30/$0.35 = 18 such groups.
Rachelle has 18 quarters and 36 nickels.
