Which costs will change with a decrease in activity within the relevant range? select one:
a. unit variable cost and unit fixed cost.
b. unit fixed costs and total variable cost
c. unit fixed cost and total fixed cost.
d. total fixed costs and total variable cost.

The correct answer is option b.  

Explanation:

The fixed costs refer to that part of the cost of production which is not affected by the volume of activity. The total fixed cost remains constant in the entire production process.

The fixed cost per unit is the ratio of total fixed costs and the level of output. It increases with a decrease in level of activity.

The variable cost is the cost incurred on the variable inputs employed in the process of production. As the level of activity declines the number of variable factors employed will also decline. This will cause the total variable cost to decrease.

a recipe serves 8 people, and calls for 5 lbs of apples and 2 cups of flour. you want to prepare it for 24 people. divide 24 by 8 to get 3, and then multiply your ingredients by 3.

so for 24 people, you'll need 15 lbs of apples, and 6 cups of flour.
