Answer: 218.75%
Explanation:
In order to breakeven, the variable manufacturing cost would have to be the same as the fixed costs in addition to the administrative costs.
= Fixed costs + Administrative cost
= 1,200,000 + 550,000
= $1,750,000
Variable cost needs to be $1,750,000
It is currently at $800,000 so it needs to increase by:
= 1,750,000 / 800,000 * 100%
= 218.75%
