Answer: $56.20
Step-by-step explanation:
Both the tax and the tips will be based on the total cost:
Tip = 43.57 * 20%
= $8.71
Tax = 43.57 * 9%
= $3.92
Total = Cost + Tip + Tax
= 43.57 + 8.71 + 3.92
= $56.20
We need to solve the speed formula for d. To do so, let's start by moving the number of the left hand side:

Square both sides to get rid of the square root:

Now plug the known value of the speed to find the distance:

So the closest answer is the last one: d=0.155km
