5 Helga signs up to coach hockey. She
lianna [129]

Answer: 12 practice sessions

Step-by-step explanation:

You can represent the word problem in this equation: 200+50x<775 OR 200+50x=775

If you subtract 200 from 775, you’ll be left with: 50x=575

Count by fifties until you get to 575. You’ll notice that 50 doesn’t go into 575 evenly! However, this won’t matter, because Helga wants to make AT LEAST 775. So you can round up to 12 practices instead of 11, which will equal 800 dollars instead of 750.
