Create a function that determines whether a shopping order is eligible for free shipping. An order is eligible for free shipping if the total cost of items purchased exceeds $50.00.

Examples

free_shipping({ "Shampoo" => 5.99, "Rubber Ducks" => 15.99 }) ➞ false

free_shipping({ "Flatscreen TV" => 399.99 }) ➞ true

free_shipping({ "Monopoly" => 11.99, "Secret Hitler" => 35.99, "Bananagrams" => 13.99 }) ➞ true

Notes

Ignore tax or additional fees when calculating the total order cost.
