7 line tshirt company manufactures t-shirts and sells them online.The company has a model where the cost C, in dollars to make x

bonufazy [111]

Answer:

The company must sell at least 2 shirts to break even.

Step-by-step explanation:

Cost:

The cost is given by the following equation:

$C = \frac{40}{30x+20} + 20 = \frac{4x}{3} + 20$

Revenue:

The revenue is given by the following equation:

$R = 15x$

How many t shirts must the company sell to break even?

Breakeven point is when the revenue is the same as the costs. So

$\frac{4x}{3} + 20 = 15x$

$15x - \frac{4x}{3} = 20$

$\frac{45x}{3} - \frac{4x}{3} = 20$

Multiplying everything by 3

$45x - 4x = 60$

$41x = 60$

$x = \frac{60}{41} = 1,...$

Since you cant make a decimal value of shirts

The company must sell at least 2 shirts to break even.

A function of the form f(x) = ab is modified so that the b value remains the same but the a value is increased by 2

pav-90 [236]

Answer:

Step-by-step explanation:

Notice that f(x) = ab would be a constant function, as 'x' does not appear on the right side. If 'a' were increased by 2, the magnitude of f(x) would be increased by a factor of 2. The domain of f(x) would not change; the range would be [a·(b+2)) (a single numeric value).
