Answer 2

Answer:

Nickels 47 & dimes 23

Step-by-step explanation:

$ 4.65= 465 cents

nickel= 5 cents

nickel= 5 centsdime= 10 cents

Let the number of nickels be = x

and of dimes be= y

So, x+y= 70

⇒x=70–y....(i)

Now, substitute this value—

5x+10y=465

⇒5(70–y)+10y=465

⇒350–5y+10y=465

⇒y=115/5=23

∴ x= 70–23=47

Therefore, the number of nickels is 47 & the number of dimes is 23.
