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.

To solve this problem, let us find the prime factors of the given numbers:

8 x 12

2 x 2 x 2 2 x 2 x 3

2⁵ x 3

144

12 x 12

2 x 2 x 3 2 x 2 x 3

2⁴ x 3²

126

2 x 63

2 7 x 9

2 3 x 3 x 7

2 x 3² x 7

So, the lowest common multiple = 2⁵ x 3² x 7 = 2016
