Question

Little Melinda has nickels and quarters in her bank. She has nine fewer nickels than quarters. She has $4.65 in the bank. How many coins of each type does she have? How many quarters does she have?​

Answer 1

Answer:

Step-by-step explanation:

n=q-9

5n+25q=465, using n from above this becomes

5(q-9)+25q=465

5q-45+25q=465

30q-45=465

30q=510

q=17, and since n=q-9

n=17-9

n=8

So Melinda has 8 nickels and 17 quarters.
