Understanding Monthly Hosting Costs

Mary Jeanne, a system administrator, calculates the monthly hosting costs for a website using web and database servers. Each web server costs $40 per month, and each database server costs $60 per month. She explores different scenarios to derive an expression for the total monthly cost, which is 40 times the number of web servers plus 60 times the number of database servers.

What is the monthly cost of one web server?

• $40

• $30

• $50

• $20

How much does one database server cost per month?

• $50

• $60

• $70

• $80

In the first scenario, what is the total monthly cost for one web server and one database server?

• $80

• $90

• $100

• $110

How much does Mary Jeanne pay for two web servers and one database server?

• $160

• $100

• $120

• $140

In the scenario with five web servers and two database servers, what is the total monthly cost?

• $300

• $400

• $600

• $500

What is the expression for calculating the monthly cost for n web servers?

• 60m

• 40m

• 60n

• 40n

What is the expression for calculating the monthly cost for m database servers?

• 40n

• 40m

• 60n

• 60m

If n is 20 and m is 10, what is the total monthly cost?

• $1000

• $1200

• $1600

• $1400

What is the total cost when n equals 15 and m equals 5?

• $900

• $1100

• $1200

• $1000

How does the expression 40n + 60m help in calculating costs?

• It calculates the cost for one server.

• It provides the total monthly cost for any number of servers.

• It only calculates the cost for database servers.

• It only calculates the cost for web servers.
