Elyess paid for her sandwich and drink with a $10 and receives $0.63 in change. the sandwich was $7.75. sales tax was 0.47.what was the cost of her drink

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 (:

step-by-step explanation:

i took the test: )

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
