$9.20

10*1.08 is 10.80. 20 - 10.80 is 9.20.

$9.20

Step-by-step explanation:

Hello, I think I can help You with this.

Step 1

find the total price of the sunscreen

Tany paid $10 + 8 % tax, it means she paid 108% of the $10, let's find that value using a rule of three

If

$10⇒100%

$x?⇒108%

the relation is

she paid $10.80

Step 2

find the difference  between $20 and $10.80 to know her change

change=$20-$10.80

change=$9.20

have a great day

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
