A manufacturer makes and sells 2 products, P and Q. The revenue from the sale of each unit of P is $20.00 and the revenue from the sale of each unit of Q is $17.00. Last year the manufacturer sold twice as many units of Q as P. What was the manufacturer's average (arithmetic mean ) revenue per unit sold of these 2 products last year?

$18

Explanation:

Since the manufacturer sold twice as many units of Q than P, that means it at least sold 1 unit of P and 2 units of Q.

to determine the arithmetic mean (average) revenue per unit:

total revenue = P + 2Q = $20 + (2 x $17) = $20 + $34 = $54

arithmetic mean (average price) = $54 / 3 = $18

answer; /// i believe that the correct answer is (b) money set aside for emergency repairs;

the answer would be voluntary exchange -

"the act of buyers and sellers freely and willingly engaging in market transactions. moreover, transactions are made in such a way that both the buyer and the seller are better off after the exchange than before it occurred."

hope this : )
