natita [175]

Step-by-step explanation:

Let x be the number of designer T shirts.

To break even,

Total Cost = Total Sales

Fixed Cost + Variable Cost = Total Sales

given the promotional advertising is classified under fixed cost,

$500 + 4.25x = 15x \\ 15x = 500 + 4.25x \\ 15x - 4.25x = 500 \\ 10.75x = 500 \\ x = 500 \div 10.75 \\ = 46.5 \\ = 47 \: (round \: off \: to \: nearest \: whole \: number)$

Solve the linear equation by combining like terms: 23 + 7 - 2x = 8x

Aleks [24]

Answer:

23+7-2x=8x

We simplify the equation to the form, which is simple to understand

23+7-2x=8x

We move all terms containing x to the left and all other terms to the right.

-2x-8x=-23-7

We simplify left and right side of the equation.

-10x=-30

We divide both sides of the equation by -10 to get x.

x=3
