Four times the amount of money in my bank account plus $200 is still two thousand dollars less than a fourth of what's in my dad's bank account. If
my dad has $20,000 in his bank account, how much money is in mine?

$700

Step-by-step explanation:

So, I like to extract the information we know and form it into an equation.

So we know that after multiplying what you have in the bank by 4, then add 200 dollars you get two thousand dollars less than a fourth of what's in your dad's bank account.

Your dad has $20,000 in the bank.

Before we write the equation let's find what two thousand less than a fourth of 20,000 is.

20,000/4 = 5,000

Now, 5,000 - 2,000 = 3,000

Ok let's say x is how much money you have

So:

4x + 200 = 3,000

we can isolate the variable by subtracting 200 from both sides

4x = 2,800

then we can divide by 4 on each side

x = 700

so you have $700 in the bank

(a) the volume of the cone is 20/3 in3

hence, option a is correct.

the first one, all those points on the line just make a strait line.
