Full Stack Homework Assignment

Build a change calculator that when given an argument of dollars and cents, output the smallest quantity of bills and coins equal to the amount.

For the candidates leaning towards the back end, you can build it in Ruby. For those leaning more towards the front end, you can build it in JavaScript.

Homework

In the USA, we have the following types of currency…

• $100 dollar bill
• $50 dollar bill
• $20 dollar bill
• $10 dollar bill
• $5 dollar bill
• $1 dollar bill
• $.25 cents (quarter)
• $.10 cents (dime)
• $.05 cents (nickel)
• $.01 cents (penny)

Example output

If 1.00 was passed as an argument, the output would be “Your change is 1 dollar bill". The dollar being the largest type of currency available to make up 100 cents, which is also the smallest quantity of dollars and coins.

If .99 was passed as an argument, the output would be “Your change is 3 quarters, 2 dimes, and 4 pennies”

if 124.67 was passed as an argument, the output would be “Your change is 1 100 dollar bill, 1 20 dollar bill, 4 1 dollar bills, 2 quarters, 1 dime, 1 nickel, and 2 pennies.
