Answer :
Given : Melissa purchased Dhs.39.46 in groceries at a store.
And
The cashier gave her Dhs.1.46 in change from Dhs.50.
Total DHs remain after shoppoing with Melissa = 50 - 39.46 = Dhs 10.54
But The cashier gave her Dhs.1.46 in change ( That is less than Dhs 10.54 ) , That 's why Melissa gave the cashier an angry look.
