Answer:
Option C is the answer.
Step-by-step explanation:
Let the quarters be q = 30
Let the dimes be d
Let the nickels be n
The ratio of her quarters to dimes is 2:3.
[tex]\frac{30}{d} =\frac{2}{3}[/tex]
We will get d from here.
[tex]2d=90[/tex]
d = 45
The ratio of her dimes to nickels is 5:3.
[tex]\frac{45}{n} =\frac{5}{3}[/tex]
Now we will get nickels from here.
[tex]5n=45\times3[/tex]
[tex]=> 5n=135[/tex]
n = 27
Hence, Ally has 27 nickels.
