Step-by-step explanation:
The original can be rewritten as

. Because i^2 is equal to -1, we can replace the -1 in each radicand with i^2, like this:

. Now, i-squared is a perfect square that can be pulled out of each radicand as a single i.

. 24 has a perfect square hidden in it. 4 * 6 = 24 and 4 is a perfect square. So let's break this up, step by step.

and then

. We will now multiply the i and the 2i, and multiply the square root of 6 times the square root of 6:

. 36 itself is a perfect square because 6 * 6 = 36. So we will do that simplification now.

. Multiplying the 2 and the 6 gives us

. But here we are back to the fact that i-squared is equal to -1, so 2(-1)(6) = -12. See how that works?
Answer:
312.5
Step-by-step explanation:
Since it is $250 plus 20 cents per poster, the equation is 0.20p+250. It is $1 per poster at store and you want to know when the cost is going to be the same so you set them equal to each other.
0.20p+250=p
250=0.80p
312.5=p
