Answer:
The total cost of her drink is $1.15 dollars.
Step-by-step explanation:
Elyess starts off with $10 dollars.
She gets $0.63 in change which means she spent a total of $9.37.
because 10 - 0.63 = 9.37.
$7.75 of the $9.37 was spent on a sandwich.
9.37 - 7.75 = $1.62. = the total amount of dollars she has right now.
Let's take off the tax.
1.62 - 0.47 = $1.15 dollars.
Everything has been taken off and we see what she has spent the money on so that means that the drink is $1.15 dollars.
Hope this helps (:
