A new health drink has 130% of the recommended daily allowance (RDA) for a certain vitamin. The RDA for this vitamin is 20 mg. How many milligrams of the vitamin are in the drink?

Answers

Answer: 58.5 milligrams

Step-by-step explanation:

Answer:

58.5 mg

Step-by-step explanation:

Drink: 130% of RDA of vitamin X

RDA vitamin X = 45 mg

130% of 45 = mg in the drink

130% of 45 = 1.3 * 45 = 58.5

Thus, this new drink has 58.5 mg of vitamin.

A car salesperson earns a monthly salary of $800 per month plus $250 for each car sold. The equation y = 250x + 800 represents the total monthly salary. Graph the equation using the slope and y-intercept.

Answers

Answer:x - the total sales

800 + 0.02 x ≥ 1600

0.02 x ≥ 1600 - 800

0.02 x ≥ 800

x ≥ 800 : 0.02

x ≥ 40,000

The total sales must be at least $40,000.

What is Equation of line?

The equation of line in point-slope form passing through the points

(x₁ , y₁) and (x₂, y₂) with slope m is defined as;

⇒ y - y₁ = m (x - x₁)

Where, m = (y₂ - y₁) / (x₂ - x₁)

Given that;

A car salesperson earns a monthly salary of $800 per month plus $250 for each car sold.

Here, The equation y = 250x + 800 represents the total monthly salary.

Hence, Slope is,

⇒ m = 250

And, Y - intercept = 800

Thus, The graph of the equation using the slope and y-intercept is shown in image.
