Answer:

Explanation:
Assume the <em>cost</em> equation to be:

Where
is the number of units (wooden baseball bats) produced.
The <em>average cost per unit of production level</em> is the total cost divided by the number of units produced:

You are given that the <em>average cost per unit of a production level of 7,700 bats is $14</em>, then:

You are also given that the <em>fixed costs</em> are <em>$22,500</em>, thus A = 22,500. Hence, you can substitute the value of A in the previous equation and find B:

Now you can complete the cost equation:

And to predict the total costs for 8,600 bats you must subsitute x with 8,600 in the previous equation:

D. foreign real national income falls and wages rates rise.
Answer:
The correct answer is to put the two variables in the same type of measure.
