Helga signs up to coach hockey. She
wants to make at least $775 during the
season. She gets $200 at the start of the
season and $50 for each practice session
she has. How many practice sessions
does Helga need to have this season?
Let x be the number of practice sessions Helga needs to have.
The total amount she wants to make is $775, so the amount she earns from practice sessions is 775 - 200 = $575.
Since she earns $50 for each practice session, the equation to represent this is:
50x = 575
Dividing both sides by 50, we get:
x = 11.5
Since Helga cannot have a fraction of a practice session, she needs to have at least 12 practice sessions this season to make at least $775.
