c. $10.

Explanation:

Suppose the government imposes a $10 per month tax on cell phone service. If the demand curve for cell phone service is perfectly inelastic and the supply curve is upward-sloping, the monthly price for cell phone service will increase by $10.

As given, the government imposes a $10 per month tax on cell phone service, which means the price of cell phone services will be costlier and increases, however, the demand curve for cell phone service is perfectly inelastic, which mean price of the product does not have any impact on the demand of the product. Then it is given the supply curve is upward sloping, which reflects the higher price of cell phone service is needed to cover the higher marginal cost of production. Therefore, the monthly price for cell phone service will increase by $10.
