**Problem 70:**  
A manufacturer of the latest basketball shoes has found that the revenue received from selling the shoes at a cost of \( p \) dollars each is given by the polynomial \( R(p) = -4p^2 + 420p \). Find the revenue received when \( p = 90 \) dollars.

---

**Problem 71:**  
The polynomial \( C(x) = 6x^2 + 90x \) gives the cost, in dollars, of producing a rectangular container whose top and bottom are squares with side \( x \) feet and height 6 feet. Find the cost of producing a box with \( x = 4 \) feet.

---

**Problem 72:**  
The polynomial \( C(x) = 6x^2 + 90x \) gives the cost, in dollars, of producing a rectangular container whose top and bottom are squares with side \( x \) feet and height 4 feet. Find the cost of producing a box with \( x = 6 \) feet.

**Add and Subtract Polynomial Functions**

In each example, find:
a. \( (f + g)(x) \)  
b. \( (f + g)(2) \)  
c. \( (f - g)(x) \)  
d. \( (f - g)(-3) \).

**Problem 73:**  
\( f(x) = 2x^2 - 4x + 1 \) and \( g(x) = 5x^2 + 8x + 3 \)

**Problem 74:**  
\( f(x) = 4x^2 - 7x + 3 \) and \( g(x) = 4x^2 + 2x - 1 \)

**Problem 75:**  
\( f(x) = 3x^3 - x^2 - 2x + 3 \) and \( g(x) = 3x^3 - 7x \)

**Problem 76:**  
\( f(x) = 5x^3 - x^2 + 3x + 4 \) and \( g(x) = 8x^3 - 1 \)
