If A monopoly firm can sell 150 units of output for $10 per unit. The marginal revenue of the 151st unit of output is $6.98.
Using this formula
Marginal revenue=(Number of units×Price per units)-(Alternate Number of units×Price per units)
Let plug in the formula
Marginal revenue=(151 units×$9.98 per units)-(150 units×$10 per units)
Marginal revenue=$1,506.98-$1,500
Marginal revenue=$6.98
Therefore the marginal revenue of the 151st unit of output is $6.98.
