The Formatter

[INCOMING — Mission Control, Earth]

Cadet, raw numbers like 9.99 print fine, but 29.970000000000002 doesn't. Real programs format numbers. f-strings can do it inline:

price = 9.99
f"${price:.2f}"   # → "$9.99"

The :.2f is a format spec: two decimal places, fixed-point.

Implement format_receipt(price, qty) that returns a 3-line string:

Item price: $<price>
Quantity: <qty>
Total: $<price * qty>

Both prices use 2-decimal formatting. Use \n to join lines.

[END TRANSMISSION]

Your Task

Open starter/starter.py. Compute total, then return a single f-string with \n separators.

Objectives

• format_receipt(9.99, 3) returns the exact 3-line string
• Prices format to 2 decimal places
• Works for any positive price and qty
