$24.50 is your original amount, and you know you have a 20% added to that. So, you can multiply the money by the percentage:
24.5 x 1.2 (we multiply it by 1.2 because we want the tip PLUS the original amount)
= 29.4
So the answer is the first choice, $29.40
Answer:

Answer: 15 minutes
Explanation:
The table is an exponential function, and the equation that represents this function is 
<h3>The equation of the table</h3>
The table is given as:
x F(x)
4 15
5 31
7 127
8 255
Rewrite the table as:
x F(x)
4 16 - 1
5 32 - 1
7 128 - 1
8 256 - 1
Express as a base of 2
x F(x)
4 2⁴ - 1
5 2⁵- 1
7 2⁷ - 1
8 2⁸ - 1
Notice that the function is 1 subtracted from 2 raised to the power of the input.
This is represented as:

Hence, the equation of the table is
