Consider the following statements regarding absorption costing and variable costing.

Total profit when added together over a ten year period will be approximately equal under absorption costing and variable costing because production and sales will be approximately the same.

Total profit when added together over a ten year period will be significantly different under absorption and variable costing because fixed costs will generally increase significantly over that long a time period.

Which statement(s) are true?
