Type Coercion in Concatenation

Medium ⏱ 12 min 49% acceptance ★★★★★ 4.6

Write a function build_receipt_line(item, qty, price) that returns a single string like "2x Coffee - $9.00", where item is a string, qty is an int, and price is a float. You must explicitly convert non-string values before concatenating — Python will not implicitly convert int/float to str with +.

Examples

Example 1

Input

build_receipt_line("Coffee", 2, 4.5)

Output

'2x Coffee - $9.00'

Explanation

qty * price = 9.0, formatted to 2 decimals.

Example 2

Input

build_receipt_line("Tea", 1, 3.0)

Output

'1x Tea - $3.00'

Explanation

Single unit purchase.

Constraints

Total = qty * price, always formatted with exactly 2 decimals.
