You are looking for what +4 = 8 so you take the 2^x and find what would make that 4. 2 squared is 4 (2x2) which makes 8=4+4

4+4=8 8=8

8 = 2^x + 4
2^x = 8 - 4
2^x = 4
as you know 4 = 2^2 so now you have:
2^x = 2^2
x = 2

Answer:

$32.3

Step-by-step explanation:

First write 30% in the decimal form

30/100 = 0.3

than the equation written in the form

x = 19 + (19 - 0.3× 19)

x = 19 + ( 19 - 5.7)

x = 19 + 13.3

x =$ 32.3

So, Kate will pay $32.3
