  $11,988

Step-by-step explanation:

A graphing calculator gives you the answer easily.

The minimum unit cost is $11,988.

__

The equation for unit cost can be put into vertex form to find the minimum.

  C(x) = 0.7x^2 -210x +27738

  C(x) = 0.7(x^2 -300x +150^2) +27738 -0.7(150^2)

  C(x) = 0.7(x -150)^2 -11,988

This is vertex form:

  C(x) = a(x -h)^2 +k . . . . . . . where (h, k) is the vertex.

The vertex of this cost function is (150, 11,988).

The minimum unit cost occurs when 150 engines are produced. That unit cost is $11,988.

Step-by-step explanation:

Lets understand the question.

Liam had $250

Cost of gift = p

Total Students = 24 (including Liam)

Each paid:

p/24 (Liam also paid this amount)

So, in terms of Liam, he would have:

250 (already had)

expended p/24 for gift, now he has:

This is amount of money Liam had left in terms of p.
