If Anika has 3 more nickels than dimes and they have a combined value of 90 cents, how many of each coin does she have?

Answer 1

Hi Chandler,

Let n= number of nickels,

d= number of dimes

from what’s given,

n=3+d

5n+10d=90

solve by substitution:

5(3+d)+10d=90

15+5d+10d=90

15+15d=90

15d=75

d=5

so, n=3+5=8

5 dimes and 8 nickels.

I hope this helps!

Answer 2

d represents the number of dimes

d + 3 represents the number of nickels

0.10d + 0.5(d + 3) = 0.90

Can you solve for d and answer?
