$10.00 per month.
a) Write an expression for the total cost of
this game.
b) What does your variable represent?
c) What type of polynomial is your expression,
and what is its degree?
d) What is the total cost if a player keeps the
subscription for 15 months?

Answer 1

The total cost of the online game can be calculated using the expression 15 + 10x, where x is the number of months played. If a player keeps the subscription for 15 months, the total cost will be $165.00.

Step-by-step explanation:

a) The expression for the total cost of the game is $15.00 (joining fee) plus $10.00 (monthly fee) multiplied by the number of months played. This can be represented as 15 + 10x, where x is the number of months played.

b) The variable x represents the number of months played.

c) The expression 15 + 10x is a linear polynomial because it has degree 1, and it represents a straight line on a graph.

d) If a player keeps the subscription for 15 months, we can plug in x = 15 into the expression. The total cost will be 15 + 10(15) = 15 + 150 = $165.00.
