Expenses that are not affected by sales volumes are called fixed costs. These costs remain constant regardless of the number of units produced or number of units sold. An example would be the lease on a building. Sales volume may fluctuate but lease payments typically remain constant (as outlined by the lease agreement).

Use a constexpr function:

constexpr float bonus (float sales)

{

return sales * 5 / 100;

}

When ATO remains constant.

* Because of the poor economy in the U.S. and Canada, most jewelry stores have constant sales or 'mark downs' on engagement rings. Shop around until you find the price you can afford.
