Buy Products

A client has purchased several products that have a certain price. Return a message with the total cost that the client needs to pay. To do that, implement a getTotalPriceMessage() function that:

• accepts three arguments: client, price, and quantity;
• returns a message in the [client] has to pay $[cost] per [quantity] products format.

For example:

val client = "Mary"
val price = 30
val quantity = 3

getTotalPriceMessage(client, price, quantity)
// returned value is "Mary has to pay $90 per 3 products"
