Answer:
B
Step-by-step explanation:
Given focus as (h,k) and directrix as y = mx + b, the equation of a parabola is given as:
Hence, from the given focus & directrix, we have:
h = -1
k = -1
m = 0
b = 1
<em>We can plug them into the formula and arrange to get:</em>
<em>
</em>

<em>B is the correct answer.</em>
To solve this problem, you have to use a proportion:
7/20 = x/100
After setting up the proportion, you have to cross multiply:
20x=700
Now, solve the equation by dividing by 20 on both sides:
x=35
So Charles has 35 laps left.
