Answer:

103

Step-by-step explanation:

We substitute x with 5:

$4(5)^2+3$

Solve the exponent first:

$5^2 = 25$

Note: We are using order of operations (consecutively)

Parentheses
Exponents
Multiplication
Division
Addition
Subtraction

Multiply:

25 * 4 = 100

Add:

100 + 3 = 103

Our answer is 103

Gymnast Clothing manufactures expensive soccer cleats for sale to college bookstores in runs of up to 500. Its cost (in dollars)

Natalija [7]

Revenue, R = 130x

Profit, P = Revenue – Cost

P = R – C

P = 130x – 2950 + 6x + 0.1x^2

At P = 0

0 = -2950 + 136x +0.1x^2

X = 21.355, -1381.355

Therefore, manufacture greater than 21.355 items to make profit.
