Answer:
120 of design B
Step-by-step explanation:
The profit per dollar cost for design A is (2500/1750 -1) ≈ 0.43. For design B, it is (2100/1200 -1) ≈ 0.75. Design B is more profitable and less expensive to make, so its production should be maximized.
For maximum profit, 120 jogging pants of design B should be made each week.
_____
The budget of 150,000 would allow 150,000/1,200 = 125 pants of design B to be made. The production limit of 120 pants does not use the entire budget.
Answer: f(-2) = 11
Concept:
Here, we need to understand the idea of evaluation.
When encountering questions that gave you an expression with variables, then stated: "If x = a, y = b, z = c" (a, b, c are all constants), this means you should substitute the value given for each variable back to the expression.
Solve:
<u>Given information</u>
f (-2) or x = -2
<u>Given function</u>
f(x) = -x² - 10x - 13
<u>Substitute values into the function</u>
f(-2) = -(-2)² - 10 (-2) - 13
<u>Simplify exponents</u>
f(-2) = -(4) - 10 (-2) - 13
<u>Simplify by multiplication</u>
f(-2) = 4 + 20 - 13
<u>Simplify by addition/subtraction</u>
f(-2) = 24 - 13
f(-2) =
