if over 600 units, fixed costs goes up 20%
how do i get each blank?

To determine the value of each blank with the given information, you would need to follow these steps:

1. Determine the initial cost of each blank: Let's assume the initial cost of each blank is X units.
2. Determine the total fixed cost before the increase: If the total fixed cost without the increase is Y units and the number of units is less than or equal to 600, then the total fixed cost would be Y units.
3. Determine the increased fixed cost: If the number of units is over 600, the fixed cost increases by 20%. Therefore, the increased fixed cost would be 20% of Y added to Y.
Increased fixed cost = Y + (0.20 * Y)
4. Calculate the number of units above 600: Subtract 600 from the total number of units to determine how many units are above 600.
Units above 600 = Total units - 600
5. Divide the increased fixed cost by the number of units above 600 to obtain the cost per unit.
Cost per unit = Increased fixed cost / Units above 600
6. Calculate the cost X per blank by dividing the cost per unit by the number of blanks per unit.
Cost per blank X = Cost per unit / Number of blanks per unit

Please note that some additional information is required to determine the values of Y, the number of units, and the number of blanks per unit.
