Answer:
The answer is $20.21
Step-by-step explanation:
So first you find the subtotal cost of the lunches. Each lunch costs $20, so that would be $40 in total.
Now you find the total cost.
She has to pay 5% sales tax so to find the total, you have to multiply 40 by 0.05. That gives you a total of $2. Then you add that to your $40 to get $42.
Now for the tip.
It says to find 10% of 20, so you have to multiply 20 by 0.1. That equals 0.208. Then you add that to 20 to get 20.208.
If you round off, you get a total of $20.21

Answer:
D
Step-by-step explanation:
A is wrong because on the point -4, the function is equal to -12 and a states the local minimum on [-4, -2] is equal to zero. Since -12 < 0, A is wrong.
B is wrong because the function never even reaches 25 on the interval [-2, -2]
C is wrong because we can see that 3.9 is zero and the function is decreasing there. fro this we can determine the functions value at x = 4 is less than 0, meaning the minimum value is also less than 0.
Lastly, we can see that the lowest point fro 4 to 7 is at -7, meaning that D is correct.
