Question

8. To watch all of the NFL games during the week, the local TV station is promoting a special. You

can get all of the games on all of your devices for a seasonal membership of $35 plus an additional $5
per game you watch.
A. Write an equation that represents the total cost of the membership.
B. Estimate how much it would cost in total if you only watched 34 games out of the season.

Answer 1

Part A

x = number of games watched

5x = cost of watching those games, ignoring the $35

5x+35 = total cost when including the $35 fee.

Answer: y = 5x+35

==============================================

Part B

Since your teacher wants an estimate, we can round 34 to 30 to make the numbers a bit nicer.

Then 5*30 = 150 which can be done with mental math. Furthermore, mental math would conclude that 150+35 = 185.

We estimate that it costs $185 to watch 35 games. This is an underestimate because we rounded 34 down to 30. To calculate an overestimate, use x = 40 in the equation we found back in part A.

Answer: $185 (underestimate)
