Answer:

$x = 5.625$

Step-by-step explanation:

Step 1: Make an expression

$\frac{3}{4} = \frac{x}{7.5}$

Step 2: Cross Multiply

$\frac{3}{4} = \frac{x}{7.5}$

$4 * x = 7.5 * 3$

$4x = 22.5$

Step 3: Divide both sides by 4

$4x / 4 = 22.5 / 4$

$x = 5.625$

Answer: $x = 5.625$

The revenue, in dollars, of a company that makes toy cars can be modeled by the polynomial 3x2 + 4x – 60. The cost, in dollars,

Tems11 [23]

For this case we have the following quadratic functions:

Revenue: $3x ^ 2 + 4x - 60$

Cost: $3x ^ 2 - x + 200$

Then, we observe that the profit is given by the following mathematical relationship:

$Profit = Revenue - Cost$

Substituting values we have:

$Profit = (3x ^ 2 + 4x - 60) - (3x ^ 2 - x + 200)$

Making the corresponding calculations we have:

$Profit = x ^ 2 (3-3) + x (4 + 1) + (-60-200)\\Profit = 5x - 260$

Answer:

An expression that represents the profit is:

$Profit = 5x - 260$
