Kay has 28 coins which includes nickels and dimes if the total is 2.35$, how many of each coin does Kay have?
m_a_m_a [10]

Answer:9 nickels and 19 dimes.

Step-by-step explanation:

Let n be the number of nickels Kay has.

Let d be the number of dimes Kay has.

Value of 1 nickel is $0.05

Value of n nickels is $0.05n

Value of 1 dime is $0.1

Value of d nickels is $0.1dn

Given that Kay has a total of 28 coins.

So,n+d=28                                                ...(i)

Given that Kay has a total value of $2.35

So,0.05n+0.1d=2.35                                 ...(ii)

Using (i) and (ii),

0.05n+0.1(28-n)=2.35\\0.05n+2.8-0.1n=2.35\\2.8-2.35=0.05n\\0.45=0.05n\\n=9

d=28-n=28-9=19
