300

Explanation:

Breakeven quantity are the number of  units produced and sold at which net income is zero

Breakeven quantity = fixed cost / price – variable cost per unit

Fixed costs are costs that do not vary with output. e,g, rent, mortgage payments

If production is zero or if production is a million, Mortgage payments do not change - it remains the same no matter the level of output.  

Hourly wage costs and payments for production inputs are variable costs

Variable costs are costs that vary with production

If a producer decides not to produce any output, there would be no need to hire labour and thus no need to pay hourly wages.

$300 / ($2 - $1) = 300
